All Known Implementing Classes:

AbstractAmazonS3, AmazonS3Client
```
public interface AmazonS3
extends S3DirectSpi
```
Provides an interface for accessing the Amazon S3 web service.

Note: Do not directly implement this interface, new methods are added to it regularly. Extend from AbstractAmazonS3 instead.

Amazon S3 provides storage for the Internet, and is designed to make web-scale computing easier for developers.

The Amazon S3 Java SDK provides a simple interface that can be used to store and retrieve any amount of data, at any time, from anywhere on the web. It gives any developer access to the same highly scalable, reliable, secure, fast, inexpensive infrastructure that Amazon uses to run its own global network of web sites. The service aims to maximize benefits of scale and to pass those benefits on to developers.

For more information about Amazon S3, please see http://aws.amazon.com/s3
Extend AbstractAmazonS3 if you are implementing AmazonS3 interface. AbstractAmazonS3 provides a default implementation for all the methods in this interface.

- Field Detail
  - ENDPOINT_PREFIX
```
static final String ENDPOINT_PREFIX
```
    The region metadata service name for computing region endpoints. You can use this value to retrieve metadata (such as supported regions) of the service.
    
    See Also:
    
    RegionUtils.getRegionsForService(String), Constant Field Values
- Method Detail
  - setEndpoint
```
void setEndpoint(String endpoint)
```
    Overrides the default endpoint for this client. Use this method to send requests to the specified Amazon Web Services region.
    
    Pass the endpoint (e.g. "s3.amazonaws.com") or a full URL, including the protocol (e.g. "https://s3.amazonaws.com"). If the protocol is not specified, the protocol from this client's ClientConfiguration is used.
    
    Parameters:
    
    endpoint - The endpoint (e.g. "s3.amazonaws.com") or the full URL, including the protocol (e.g. "https://s3.amazonaws.com"), of the region-specific Amazon Web Services endpoint this client will communicate with.
    
    Throws:
    
    IllegalArgumentException - If the specified endpoint is not a valid URL endpoint.
  - setRegion
```
void setRegion(Region region)
        throws IllegalArgumentException
```
    An alternative to AmazonS3.setEndpoint(String), sets the regional endpoint for this client's service calls. Callers can use this method to control which Amazon Web Services region they want to work with.
    This method is not threadsafe. A region should be configured when the client is created and before any service requests are made. Changing it afterwards creates inevitable race conditions for any service requests in transit or retrying.
    By default, all service endpoints in all regions use the https protocol. To use http instead, specify it in the ClientConfiguration supplied at construction.
    
    Parameters:
    
    region - The region this client will communicate with. See Region.getRegion(com.ibm.cloud.objectstorage.regions.Regions) for accessing a given region.
    
    Throws:
    
    IllegalArgumentException - If the given region is null, or if this service isn't available in the given region. See Region.isServiceSupported(String)
    
    See Also:

```
void setS3ClientOptions(S3ClientOptions clientOptions)
```

                   throws SdkClientException,
                          AmazonServiceException
```
    Returns a list of summary information about the objects in the specified buckets. List results are always returned in lexicographic (alphabetical) order.
    
    Because buckets can contain a virtually unlimited number of keys, the complete results of a list query can be extremely large. To manage large result sets, Amazon S3 uses pagination to split them into multiple responses. Always check the ObjectListing.isTruncated() method to see if the returned listing is complete or if additional calls are needed to get more results. Alternatively, use the AmazonS3Client.listNextBatchOfObjects(ObjectListing) method as an easy way to get the next page of object listings.
    
    The total number of keys in a bucket doesn't substantially affect list performance.
    
    Parameters:
    
    bucketName - The name of the Amazon S3 bucket to list.
    
    Returns:
    
    A listing of the objects in the specified bucket, along with any other associated information, such as common prefixes (if a delimiter was specified), the original request parameters, etc.
    
    Throws:
    
    SdkClientException - If any errors are encountered in the client while making the request or handling the response.
    
    AmazonServiceException - If any errors occurred in Amazon S3 while processing the request.

ObjectListing listObjects(String bucketName,
                          String prefix)
                   throws SdkClientException,
                          AmazonServiceException
```
    Returns a list of summary information about the objects in the specified bucket. Depending on request parameters, additional information is returned, such as common prefixes if a delimiter was specified. List results are always returned in lexicographic (alphabetical) order.
    
    Because buckets can contain a virtually unlimited number of keys, the complete results of a list query can be extremely large. To manage large result sets, Amazon S3 uses pagination to split them into multiple responses. Always check the ObjectListing.isTruncated() method to see if the returned listing is complete or if additional calls are needed to get more results. Alternatively, use the AmazonS3Client.listNextBatchOfObjects(ObjectListing) method as an easy way to get the next page of object listings.
    
    For example, consider a bucket that contains the following keys:
    - "foo/bar/baz"
    - "foo/bar/bash"
    - "foo/bar/bang"
    - "foo/boo"
    If calling listObjects with a prefix value of "foo/" and a delimiter value of "/" on this bucket, an ObjectListing is returned that contains one key ("foo/boo") and one entry in the common prefixes list ("foo/bar/"). To see deeper into the virtual hierarchy, make another call to listObjects setting the prefix parameter to any interesting common prefix to list the individual keys under that prefix.
    
    The total number of keys in a bucket doesn't substantially affect list performance.
    Parameters:
    
    bucketName - The name of the Amazon S3 bucket to list.
    
    prefix - An optional parameter restricting the response to keys beginning with the specified prefix. Use prefixes to separate a bucket into different sets of keys, similar to how a file system organizes files into directories.
    
    Returns:
    
    A listing of the objects in the specified bucket, along with any other associated information, such as common prefixes (if a delimiter was specified), the original request parameters, etc.
    
    Throws:
    
    SdkClientException - If any errors are encountered in the client while making the request or handling the response.
    
    AmazonServiceException - If any errors occurred in Amazon S3 while processing the request.

                          AmazonServiceException
```
    Returns a list of summary information about the objects in the specified bucket. Depending on the request parameters, additional information is returned, such as common prefixes if a delimiter was specified. List results are always returned in lexicographic (alphabetical) order.
    
    Because buckets can contain a virtually unlimited number of keys, the complete results of a list query can be extremely large. To manage large result sets, Amazon S3 uses pagination to split them into multiple responses. Always check the ObjectListing.isTruncated() method to see if the returned listing is complete or if additional calls are needed to get more results. Alternatively, use the AmazonS3Client.listNextBatchOfObjects(ObjectListing) method as an easy way to get the next page of object listings.
    
    Calling ListObjectsRequest.setDelimiter(String) sets the delimiter, allowing groups of keys that share the delimiter-terminated prefix to be included in the returned listing. This allows applications to organize and browse their keys hierarchically, similar to how a file system organizes files into directories. These common prefixes can be retrieved through the ObjectListing.getCommonPrefixes() method.
    
    For example, consider a bucket that contains the following keys:
    - "foo/bar/baz"
    - "foo/bar/bash"
    - "foo/bar/bang"
    - "foo/boo"
    If calling listObjects with a prefix value of "foo/" and a delimiter value of "/" on this bucket, an ObjectListing is returned that contains one key ("foo/boo") and one entry in the common prefixes list ("foo/bar/"). To see deeper into the virtual hierarchy, make another call to listObjects setting the prefix parameter to any interesting common prefix to list the individual keys under that prefix.
    
    The total number of keys in a bucket doesn't substantially affect list performance.
    Parameters:
    
    listObjectsRequest - The request object containing all options for listing the objects in a specified bucket.
    
    Returns:
    
    A listing of the objects in the specified bucket, along with any other associated information, such as common prefixes (if a delimiter was specified), the original request parameters, etc.
    
    Throws:
    
    SdkClientException - If any errors are encountered in the client while making the request or handling the response.
    
    AmazonServiceException - If any errors occurred in Amazon S3 while processing the request.

    Returns a list of summary information about the versions in the specified bucket.
    
    The returned version summaries are ordered first by key and then by version. Keys are sorted lexicographically (alphabetically) and versions are sorted from most recent to least recent. Versions with data and delete markers are included in the results.
    
    Because buckets can contain a virtually unlimited number of versions, the complete results of a list query can be extremely large. To manage large result sets, Amazon S3 uses pagination to split them into multiple responses. Always check the VersionListing.isTruncated() method to determine if the returned listing is complete or if additional calls are needed to get more results. Callers are encouraged to use AmazonS3.listNextBatchOfVersions(VersionListing) as an easy way to get the next page of results.
    
    The keyMarker and versionIdMarker parameters allow callers to specify where to start the version listing.
    
    The delimiter parameter allows groups of keys that share a delimiter-terminated prefix to be included in the returned listing. This allows applications to organize and browse their keys hierarchically, much like how a file system organizes files into directories. These common prefixes can be retrieved by calling the VersionListing.getCommonPrefixes() method.
    
    For example, consider a bucket that contains the following keys:
    - "foo/bar/baz"
    - "foo/bar/bash"
    - "foo/bar/bang"
    - "foo/boo"
    If calling listVersions with a prefix value of "foo/" and a delimiter value of "/" on this bucket, a VersionListing is returned that contains:
    - all the versions for one key ("foo/boo")
    - one entry in the common prefixes list ("foo/bar/")
    To see deeper into the virtual hierarchy, make another call to listVersions setting the prefix parameter to any interesting common prefix to list the individual versions under that prefix.
    
    For more information about enabling versioning for a bucket, see AmazonS3.setBucketVersioningConfiguration(SetBucketVersioningConfigurationRequest).
    Parameters:
    
    bucketName - The name of the Amazon S3 bucket whose versions are to be listed.
    
    prefix - An optional parameter restricting the response to keys that begin with the specified prefix. Use prefixes to separate a bucket into different sets of keys, similar to how a file system organizes files into directories.
    
    keyMarker - Optional parameter indicating where in the sorted list of all versions in the specified bucket to begin returning results. Results are always ordered first lexicographically (i.e. alphabetically) and then from most recent version to least recent version. If a keyMarker is used without a versionIdMarker, results begin immediately after that key's last version. When a keyMarker is used with a versionIdMarker, results begin immediately after the version with the specified key and version ID.
    This enables pagination; to get the next page of results use the next key marker and next version ID marker (from VersionListing.getNextKeyMarker() and VersionListing.getNextVersionIdMarker()) as the markers for the next request to list versions, or use the convenience method AmazonS3.listNextBatchOfVersions(VersionListing)
    
    versionIdMarker - Optional parameter indicating where in the sorted list of all versions in the specified bucket to begin returning results. Results are always ordered first lexicographically (i.e. alphabetically) and then from most recent version to least recent version. A keyMarker must be specified when specifying a versionIdMarker. Results begin immediately after the version with the specified key and version ID.
    This enables pagination; to get the next page of results use the next key marker and next version ID marker (from VersionListing.getNextKeyMarker() and VersionListing.getNextVersionIdMarker()) as the markers for the next request to list versions, or use the convenience method AmazonS3.listNextBatchOfVersions(VersionListing)
    
    delimiter - Optional parameter that causes keys that contain the same string between the prefix and the first occurrence of the delimiter to be rolled up into a single result element in the VersionListing.getCommonPrefixes() list. These rolled-up keys are not returned elsewhere in the response. The most commonly used delimiter is "/", which simulates a hierarchical organization similar to a file system directory structure.
    
    maxResults - Optional parameter indicating the maximum number of results to include in the response. Amazon S3 might return fewer than this, but will not return more. Even if maxKeys is not specified, Amazon S3 will limit the number of results in the response.
    
    Returns:
    
    A listing of the versions in the specified bucket, along with any other associated information such as common prefixes (if a delimiter was specified), the original request parameters, etc.
    
    Throws:
    
    SdkClientException - If any errors are encountered in the client while making the request or handling the response.
    
    AmazonServiceException - If any errors occurred in Amazon S3 while processing the request.

    Deprecated. By AmazonS3.doesBucketExistV2(String) which will correctly throw an exception when credentials are invalid instead of returning true. See Issue #1256.
    
    Checks if the specified bucket exists. Amazon S3 buckets are named in a global namespace; use this method to determine if a specified bucket name already exists, and therefore can't be used to create a new bucket. If invalid security credentials are used to execute this method, the client is not able to distinguish between bucket permission errors and invalid credential errors, and this method could return an incorrect result.
    Internally this uses the AmazonS3.headBucket(HeadBucketRequest) operation to determine whether the bucket exists.
    
    Parameters:
    
    bucketName - The name of the bucket to check.
    
    Returns:
    
    The value true if the specified bucket exists in Amazon S3; the value false if there is no bucket in Amazon S3 with that name.
    
    Throws:
    
    SdkClientException - If any errors are encountered in the client while making the request or handling the response.

    Internally this uses the AmazonS3.getBucketAcl(String) operation to determine whether the bucket exists.
    
    Parameters:
    
    bucketName - The name of the bucket to check.
    
    Returns:
    
    The value true if the specified bucket exists in Amazon S3; the value false if there is no bucket in Amazon S3 with that name.
    
    Throws:
    
    SdkClientException - If any errors are encountered in the client while making the request or handling the response.
    
    AmazonServiceException - If any errors occurred in Amazon S3 while processing the request.

```
    This action is useful to determine if a bucket exists and you have permission to access it. The action returns a 200 OK if the bucket exists and you have permission to access it.
    
    If the bucket does not exist or you do not have permission to access it, the HEAD request returns a generic 400 Bad Request, 403 Forbidden or 404 Not Found code. A message body is not included, so you cannot determine the exception beyond these error codes.
    
    To use this operation, you must have permissions to perform the s3:ListBucket action. The bucket owner has this permission by default and can grant this permission to others. For more information about permissions, see Permissions Related to Bucket Subresource Operations and Managing Access Permissions to Your Amazon S3 Resources.
    
    To use this API against an access point, you must provide the alias of the access point in place of the bucket name or specify the access point ARN. When using the access point ARN, you must direct requests to the access point hostname. The access point hostname takes the form AccessPointName-AccountId.s3-accesspoint.Region.amazonaws.com. When using the Amazon Web Services SDKs, you provide the ARN in place of the bucket name. For more information see, Using access points.
    
    Parameters:
    
    headBucketRequest - The request containing the bucket name.
    
    Returns:
    
    This method returns a HeadBucketResult if the bucket exists and you have permission to access it. Otherwise, the method will throw an AmazonServiceException with status code '404 Not Found' if the bucket does not exist, '403 Forbidden' if the user does not have access to the bucket, or '301 Moved Permanently' if the bucket is in a different region than the client is configured with
    
    Throws:
    
    SdkClientException - If any errors are encountered in the client while making the request or handling the response.
    
    AmazonServiceException - If any errors occurred in Amazon S3 while processing the request.

Bucket createBucket(CreateBucketRequest createBucketRequest)
             throws SdkClientException,
                    AmazonServiceException
```
    Creates a new S3 bucket. To create a bucket, you must register with Amazon S3 and have a valid Amazon Web Services Access Key ID to authenticate requests. Anonymous requests are never allowed to create buckets. By creating the bucket, you become the bucket owner.
    
    Not every string is an acceptable bucket name. For information about bucket naming restrictions, see Bucket naming rules.
    
    If you want to create an Amazon S3 on Outposts bucket, see Create Bucket.
    
    By default, the bucket is created in the US East (N. Virginia) Region. You can optionally specify a Region in the request body. You might choose a Region to optimize latency, minimize costs, or address regulatory requirements. For example, if you reside in Europe, you will probably find it advantageous to create buckets in the Europe (Ireland) Region. For more information, see Accessing a bucket.
    
    If you send your create bucket request to the s3.amazonaws.com endpoint, the request goes to the us-east-1 Region. Accordingly, the signature calculations in Signature Version 4 must use us-east-1 as the Region, even if the location constraint in the request specifies another Region where the bucket is to be created. If you create a bucket in a Region other than US East (N. Virginia), your application must be able to handle 307 redirect. For more information, see Virtual hosting of buckets.
    
    Access control lists (ACLs)
    
    When creating a bucket using this operation, you can optionally configure the bucket ACL to specify the accounts or groups that should be granted specific permissions on the bucket.
    
    If your CreateBucket request sets bucket owner enforced for S3 Object Ownership and specifies a bucket ACL that provides access to an external Amazon Web Services account, your request fails with a 400 error and returns the InvalidBucketAclWithObjectOwnership error code. For more information, see Controlling object ownership in the Amazon S3 User Guide.
    
    There are two ways to grant the appropriate permissions using the request headers.
    - Specify a canned ACL using the x-amz-acl request header. Amazon S3 supports a set of predefined ACLs, known as canned ACLs. Each canned ACL has a predefined set of grantees and permissions. For more information, see Canned ACL.
    - Specify access permissions explicitly using the x-amz-grant-read, x-amz-grant-write, x-amz-grant-read-acp, x-amz-grant-write-acp, and x-amz-grant-full-control headers. These headers map to the set of permissions Amazon S3 supports in an ACL. For more information, see Access control list (ACL) overview.
      
      You specify each grantee as a type=value pair, where the type is one of the following:
      
      id – if the value specified is the canonical user ID of an Amazon Web Services account
      
      uri – if you are granting permissions to a predefined group
      
      emailAddress – if the value specified is the email address of an Amazon Web Services account
      
      Using email addresses to specify a grantee is only supported in the following Amazon Web Services Regions:
      
      US East (N. Virginia)
      
      US West (N. California)
      
      US West (Oregon)
      
      Asia Pacific (Singapore)
      
      Asia Pacific (Sydney)
      
      Asia Pacific (Tokyo)
      
      Europe (Ireland)
      
      South America (São Paulo)
      
      For a list of all the Amazon S3 supported Regions and endpoints, see Regions and Endpoints in the Amazon Web Services General Reference.
      
      For example, the following x-amz-grant-read header grants the Amazon Web Services accounts identified by account IDs permissions to read object data and its metadata:
      
      x-amz-grant-read: id="11112222333", id="444455556666"
    You can use either a canned ACL or specify access permissions explicitly. You cannot do both.
    
    Permissions
    
    In addition to s3:CreateBucket, the following permissions are required when your CreateBucket includes specific headers:
    - ACLs - If your CreateBucket request specifies ACL permissions and the ACL is public-read, public-read-write, authenticated-read, or if you specify access permissions explicitly through any other ACL, both s3:CreateBucket and s3:PutBucketAcl permissions are needed. If the ACL the CreateBucket request is private or doesn't specify any ACLs, only s3:CreateBucket permission is needed.
    - Object Lock - If ObjectLockEnabledForBucket is set to true in your CreateBucket request, s3:PutBucketObjectLockConfiguration and s3:PutBucketVersioning permissions are required.
    - S3 Object Ownership - If your CreateBucket request includes the the x-amz-object-ownership header, s3:PutBucketOwnershipControls permission is required.
    The following operations are related to CreateBucket:
    - PutObject
    - DeleteBucket
    Parameters:
    
    createBucketRequest - The request object containing all options for creating an Amazon S3 bucket.
    
    Returns:
    
    The newly created bucket.
    
    Throws:
    
    SdkClientException - If any errors are encountered in the client while making the request or handling the response.
    
    AmazonServiceException - If any errors occurred in Amazon S3 while processing the request.

```
    Deprecated. Use regional endpoint and call AmazonS3.createBucket(String) instead.
    Creates a new Amazon S3 bucket with the specified name in the specified Amazon S3 region.
    
    Every object stored in Amazon S3 is contained within a bucket. Buckets partition the namespace of objects stored in Amazon S3 at the top level. Within a bucket, any name can be used for objects. However, bucket names must be unique across all of Amazon S3.
    
    Bucket ownership is similar to the ownership of Internet domain names. Within Amazon S3, only a single user owns each bucket. Once a uniquely named bucket is created in Amazon S3, organize and name the objects within the bucket in any way. Ownership of the bucket is retained as long as the owner has an Amazon S3 account.
    
    To conform with DNS requirements, the following constraints apply:
    - Bucket names should not contain underscores
    - Bucket names should be between 3 and 63 characters long
    - Bucket names should not end with a dash
    - Bucket names cannot contain adjacent periods
    - Bucket names cannot contain dashes next to periods (e.g., "my-.bucket.com" and "my.-bucket" are invalid)
    - Bucket names cannot contain uppercase characters
    There are no limits to the number of objects that can be stored in a bucket. Performance does not vary based on the number of buckets used. Store all objects within a single bucket or organize them across several buckets.
    
    Buckets cannot be nested; buckets cannot be created within other buckets.
    
    Do not make bucket create or delete calls in the high availability code path of an application. Create or delete buckets in a separate initialization or setup routine that runs less often.
    
    To create a bucket, authenticate with an account that has a valid Amazon Web Services Access Key ID and is registered with Amazon S3. Anonymous requests are never allowed to create buckets.
    Parameters:
    
    bucketName - The name of the bucket to create.
    
    region - The Amazon S3 region in which to create the new bucket.
    
    Returns:

                  AmazonServiceException
```
    Sets the CannedAccessControlList for the specified object in Amazon S3 using one of the pre-configured CannedAccessControlLists. A CannedAccessControlList provides a quick way to configure an object or bucket with commonly used access control policies.
    
    Each bucket and object in Amazon S3 has an ACL that defines its access control policy. When a request is made, Amazon S3 authenticates the request using its standard authentication procedure and then checks the ACL to verify the sender was granted access to the bucket or object. If the sender is approved, the request proceeds. Otherwise, Amazon S3 returns an error.
    
    Parameters:
    
    bucketName - The name of the bucket containing the object whose ACL is being set.
    
    key - The key of the object within the specified bucket whose ACL is being set.
    
    acl - The new pre-configured CannedAccessControlList for the specified object.
    
    Throws:
    
    SdkClientException - If any errors are encountered in the client while making the request or handling the response.
    
    AmazonServiceException - If any errors occurred in Amazon S3 while processing the request.

    Gets the metadata for the specified Amazon S3 object without actually fetching the object itself. This is useful in obtaining only the object metadata, and avoids wasting bandwidth on fetching the object data.
    
    The object metadata contains information such as content type, content disposition, etc., as well as custom user metadata that can be associated with an object in Amazon S3.
    
    Parameters:
    
    bucketName - The name of the bucket containing the object's whose metadata is being retrieved.
    
    key - The key of the object whose metadata is being retrieved.
    
    Returns:
    
    All Amazon S3 object metadata for the specified object.

```
    The HEAD action retrieves metadata from an object without returning the object itself. This action is useful if you're only interested in an object's metadata. To use HEAD, you must have READ access to the object.
    
    A HEAD request has the same options as a GET action on an object. The response is identical to the GET response except that there is no response body. Because of this, if the HEAD request generates an error, it returns a generic 400 Bad Request, 403 Forbidden or 404 Not Found code. It is not possible to retrieve the exact exception beyond these error codes.
    
    If you encrypt an object by using server-side encryption with customer-provided encryption keys (SSE-C) when you store the object in Amazon S3, then when you retrieve the metadata from the object, you must use the following headers:
    - x-amz-server-side-encryption-customer-algorithm
    - x-amz-server-side-encryption-customer-key
    - x-amz-server-side-encryption-customer-key-MD5
    For more information about SSE-C, see Server-Side Encryption (Using Customer-Provided Encryption Keys).
    Encryption request headers, like x-amz-server-side-encryption, should not be sent for GET requests if your object uses server-side encryption with CMKs stored in Amazon Web Services KMS (SSE-KMS) or server-side encryption with Amazon S3–managed keys (SSE-S3). If your object does use these types of keys, you’ll get an HTTP 400 BadRequest error.
    
    The last modified property in this case is the creation date of the object.
    Request headers are limited to 8 KB in size. For more information, see Common Request Headers.
    
    Consider the following when using request headers:
    - Consideration 1 – If both of the If-Match and If-Unmodified-Since headers are present in the request as follows:
      
      If-Match condition evaluates to true, and;
      
      If-Unmodified-Since condition evaluates to false;
      
      Then Amazon S3 returns 200 OK and the data requested.
    - Consideration 2 – If both of the If-None-Match and If-Modified-Since headers are present in the request as follows:
      
      If-None-Match condition evaluates to false, and;
      
      If-Modified-Since condition evaluates to true;
      
      Then Amazon S3 returns the 304 Not Modified response code.
    For more information about conditional requests, see RFC 7232.
    
    Permissions
    < p>You need the relevant read object (or version) permission for this operation. For more information, see Specifying Permissions in a Policy. If the object you request does not exist, the error Amazon S3 returns depends on whether you also have the s3:ListBucket permission.
    - If you have the s3:ListBucket permission on the bucket, Amazon S3 returns an HTTP status code 404 (\"no such key\") error.
    - If you don’t have the s3:ListBucket permission, Amazon S3 returns an HTTP status code 403 (\"access denied\") error.
    The following action is related to HeadObject:
    - GetObject
    Parameters:
    
    getObjectMetadataRequest - The request object specifying the bucket, key and optional version ID of the object whose metadata is being retrieved.
    
    Returns:
    
    All S3 object metadata for the specified object.
    
    Throws:
    
    SdkClientException - If any errors are encountered on the client while making the request or handling the response.
    
    AmazonServiceException - If any errors occurred in Amazon S3 while processing the request.

S3Object getObject(String bucketName,
                   String key)
            throws SdkClientException,
                   AmazonServiceException
```
    Retrieves objects from Amazon S3. To use GET, you must have READ access to the object. If you grant READ access to the anonymous user, you can return the object without using an authorization header.
    
    An Amazon S3 bucket has no directory hierarchy such as you would find in a typical computer file system. You can, however, create a logical hierarchy by using object key names that imply a folder structure. For example, instead of naming an object sample.jpg, you can name it photos/2006/February/sample.jpg.
    
    To get an object from such a logical hierarchy, specify the full key name for the object in the GET operation. For a virtual hosted-style request example, if you have the object photos/2006/February/sample.jpg, specify the resource as /photos/2006/February/sample.jpg. For a path-style request example, if you have the object photos/2006/February/sample.jpg in the bucket named examplebucket, specify the resource as /examplebucket/photos/2006/February/sample.jpg. For more information about request types, see HTTP Host Header Bucket Specification.
    
    For more information about returning the ACL of an object, see GetObjectAcl.
    
    If the object you are retrieving is stored in the S3 Glacier or S3 Glacier Deep Archive storage class, or S3 Intelligent-Tiering Archive or S3 Intelligent-Tiering Deep Archive tiers, before you can retrieve the object you must first restore a copy using RestoreObject. Otherwise, this action returns an InvalidObjectState error. For information about restoring archived objects, see Restoring Archived Objects.
    
    Encryption request headers, like x-amz-server-side-encryption, should not be sent for GET requests if your object uses server-side encryption with KMS keys (SSE-KMS) or server-side encryption with Amazon S3–managed encryption keys (SSE-S3). If your object does use these types of keys, you’ll get an HTTP 400 BadRequest error.
    
    If you encrypt an object by using server-side encryption with customer-provided encryption keys (SSE-C) when you store the object in Amazon S3, then when you GET the object, you must use the following headers:
    - x-amz-server-side-encryption-customer-algorithm
    - x-amz-server-side-encryption-customer-key
    - x-amz-server-side-encryption-customer-key-MD5
    For more information about SSE-C, see Server-Side Encryption (Using Customer-Provided Encryption Keys).
    
    Assuming you have the relevant permission to read object tags, the response also returns the x-amz-tagging-count header that provides the count of number of tags associated with the object. You can use GetObjectTagging to retrieve the tag set associated with an object.
    
    Permissions
    
    You need the relevant read object (or version) permission for this operation. For more information, see Specifying Permissions in a Policy. If the object you request does not exist, the error Amazon S3 returns depends on whether you also have the s3:ListBucket permission.
    - If you have the s3:ListBucket permission on the bucket, Amazon S3 will return an HTTP status code 404 ("no such key") error.
    - If you don’t have the s3:ListBucket permission, Amazon S3 will return an HTTP status code 403 ("access denied") error.
    Versioning
    
    By default, the GET action returns the current version of an object. To return a different version, use the versionId subresource.
    If you supply a versionId, you need the s3:GetObjectVersion permission to access a specific version of an object. If you request a specific version, you do not need to have the s3:GetObject permission. If you request the current version without a specific version ID, only s3:GetObject permission is required. s3:GetObjectVersion permission won't be required.
    
    If the current version of the object is a delete marker, Amazon S3 behaves as if the object was deleted and includes x-amz-delete-marker: true in the response.
    For more information about versioning, see PutBucketVersioning.
    
    Overriding Response Header Values
    
    There are times when you want to override certain response header values in a GET response. For example, you might override the Content-Disposition response header value in your GET request.
    
    You can override values for a set of response headers using the following query parameters. These response header values are sent only on a successful request, that is, when status code 200 OK is returned. The set of headers you can override using these parameters is a subset of the headers that Amazon S3 accepts when you create an object. The response headers that you can override for the GET response are Content-Type, Content-Language, Expires, Cache-Control, Content-Disposition , and Content-Encoding. To override these header values in the GET response, you use the following request parameters.
    
    You must sign the request, either using an Authorization header or a presigned URL, when using these parameters. They cannot be used with an unsigned (anonymous) request.
    - response-content-type
    - response-content-language
    - response-expires
    - response-cache-control
    - response-content-disposition
    - response-content-encoding
    Additional Considerations about Request Headers
    
    If both of the If-Match and If-Unmodified-Since headers are present in the request as follows: If-Match condition evaluates to true, and; If-Unmodified-Since condition evaluates to false; then, S3 returns 200 OK and the data requested.
    
    If both of the If-None-Match and If-Modified-Since headers are present in the request as follows: If-None-Match condition evaluates to false, and; If-Modified-Since condition evaluates to true; then, S3 returns 304 Not Modified response code.
    
    For more information about conditional requests, see RFC 7232.

    An Amazon S3 bucket has no directory hierarchy such as you would find in a typical computer file system. You can, however, create a logical hierarchy by using object key names that imply a folder structure. For example, instead of naming an object sample.jpg, you can name it photos/2006/February/sample.jpg.
    
    To get an object from such a logical hierarchy, specify the full key name for the object in the GET operation. For a virtual hosted-style request example, if you have the object photos/2006/February/sample.jpg, specify the resource as /photos/2006/February/sample.jpg. For a path-style request example, if you have the object photos/2006/February/sample.jpg in the bucket named examplebucket, specify the resource as /examplebucket/photos/2006/February/sample.jpg. For more information about request types, see HTTP Host Header Bucket Specification.
    
    For more information about returning the ACL of an object, see GetObjectAcl.
    
    If the object you are retrieving is stored in the S3 Glacier or S3 Glacier Deep Archive storage class, or S3 Intelligent-Tiering Archive or S3 Intelligent-Tiering Deep Archive tiers, before you can retrieve the object you must first restore a copy using RestoreObject. Otherwise, this action returns an InvalidObjectState error. For information about restoring archived objects, see Restoring Archived Objects.
    
    Encryption request headers, like x-amz-server-side-encryption, should not be sent for GET requests if your object uses server-side encryption with KMS keys (SSE-KMS) or server-side encryption with Amazon S3–managed encryption keys (SSE-S3). If your object does use these types of keys, you’ll get an HTTP 400 BadRequest error.
    
    If you encrypt an object by using server-side encryption with customer-provided encryption keys (SSE-C) when you store the object in Amazon S3, then when you GET the object, you must use the following headers:
    - x-amz-server-side-encryption-customer-algorithm
    - x-amz-server-side-encryption-customer-key
    - x-amz-server-side-encryption-customer-key-MD5
    For more information about SSE-C, see Server-Side Encryption (Using Customer-Provided Encryption Keys).
    
    Assuming you have the relevant permission to read object tags, the response also returns the x-amz-tagging-count header that provides the count of number of tags associated with the object. You can use GetObjectTagging to retrieve the tag set associated with an object.
    
    Permissions
    
    You need the relevant read object (or version) permission for this operation. For more information, see Specifying Permissions in a Policy. If the object you request does not exist, the error Amazon S3 returns depends on whether you also have the s3:ListBucket permission.
    - If you have the s3:ListBucket permission on the bucket, Amazon S3 will return an HTTP status code 404 ("no such key") error.
    - If you don’t have the s3:ListBucket permission, Amazon S3 will return an HTTP status code 403 ("access denied") error.
    Versioning
    
    By default, the GET action returns the current version of an object. To return a different version, use the versionId subresource.
    If you supply a versionId, you need the s3:GetObjectVersion permission to access a specific version of an object. If you request a specific version, you do not need to have the s3:GetObject permission. If you request the current version without a specific version ID, only s3:GetObject permission is required. s3:GetObjectVersion permission won't be required.
    
    If the current version of the object is a delete marker, Amazon S3 behaves as if the object was deleted and includes x-amz-delete-marker: true in the response.
    For more information about versioning, see PutBucketVersioning.
    
    Overriding Response Header Values
    
    There are times when you want to override certain response header values in a GET response. For example, you might override the Content-Disposition response header value in your GET request.
    
    You can override values for a set of response headers using the following query parameters. These response header values are sent only on a successful request, that is, when status code 200 OK is returned. The set of headers you can override using these parameters is a subset of the headers that Amazon S3 accepts when you create an object. The response headers that you can override for the GET response are Content-Type, Content-Language, Expires, Cache-Control, Content-Disposition , and Content-Encoding. To override these header values in the GET response, you use the following request parameters.
    
    You must sign the request, either using an Authorization header or a presigned URL, when using these parameters. They cannot be used with an unsigned (anonymous) request.
    - response-content-type
    - response-content-language
    - response-expires
    - response-cache-control
    - response-content-disposition
    - response-content-encoding
    Additional Considerations about Request Headers
    
    If both of the If-Match and If-Unmodified-Since headers are present in the request as follows: If-Match condition evaluates to true, and; If-Unmodified-Since condition evaluates to false; then, S3 returns 200 OK and the data requested.
    
    If both of the If-None-Match and If-Modified-Since headers are present in the request as follows: If-None-Match condition evaluates to false, and; If-Modified-Since condition evaluates to true; then, S3 returns 304 Not Modified response code.

```
    Uploads a new object to the specified Amazon S3 bucket. The PutObjectRequest contains all the details of the request, including the bucket to upload to, the key the object will be uploaded under, and the file or input stream containing the data to upload.
    
    Amazon S3 never stores partial objects; if during this call an exception wasn't thrown, the entire object was stored.
    
    If you are uploading or accessing Amazon Web Services KMS-encrypted objects, you need to specify the correct region of the bucket on your client and configure Amazon Web Services Signature Version 4 for added security. For more information on how to do this, see http://docs.aws.amazon.com/AmazonS3/latest/dev/UsingAWSSDK.html# specify-signature-version
    
    Depending on whether a file or input stream is being uploaded, this method has slightly different behavior.
    
    When uploading a file:
    - The client automatically computes a checksum of the file. Amazon S3 uses checksums to validate the data in each file.
    - Using the file extension, Amazon S3 attempts to determine the correct content type and content disposition to use for the object.
    When uploading directly from an input stream:
    - Be careful to set the correct content type in the metadata object before directly sending a stream. Unlike file uploads, content types from input streams cannot be automatically determined. If the caller doesn't explicitly set the content type, it will not be set in Amazon S3.
    - Content length must be specified before data can be uploaded to Amazon S3. Amazon S3 explicitly requires that the content length be sent in the request headers before it will accept any of the data. If the caller doesn't provide the length, the library must buffer the contents of the input stream in order to calculate it.
    If versioning is enabled for the specified bucket, this operation will never overwrite an existing object with the same key, but will keep the existing object as an older version until that version is explicitly deleted (see AmazonS3.deleteVersion(String, String, String).
    
    If versioning is not enabled, this operation will overwrite an existing object with the same key; Amazon S3 will store the last write request. Amazon S3 does not provide object locking. If Amazon S3 receives multiple write requests for the same object nearly simultaneously, all of the objects might be stored. However, a single object will be stored with the final write request.
    
    When specifying a location constraint when creating a bucket, all objects added to the bucket are stored in the bucket's region. For example, if specifying a Europe (EU) region constraint for a bucket, all of that bucket's objects are stored in the EU region.
    
    The specified bucket must already exist and the caller must have Permission.Write permission to the bucket to upload an object.
    Specified by:
    
    putObject in interface S3DirectSpi
    
    Parameters:
    
    putObjectRequest - The request object containing all the parameters to upload a new object to Amazon S3.
    
    Returns:
    
    A PutObjectResult object containing the information returned by Amazon S3 for the newly created object.
    
    Throws:
    
    SdkClientException - If any errors are encountered in the client while making the request or handling the response.

    The client automatically computes a checksum of the file. This checksum is verified against another checksum that is calculated once the data reaches Amazon S3, ensuring the data has not corrupted in transit over the network.
    
    Using the file extension, Amazon S3 attempts to determine the correct content type and content disposition to use for the object.
    
    Content length must be specified before data can be uploaded to Amazon S3. If the caller doesn't provide it, the library will make a best effort to compute the content length by buffer the contents of the input stream into the memory because Amazon S3 explicitly requires that the content length be sent in the request headers before any of the data is sent. Please note that this operation is not guaranteed to succeed.
    
    When using an BufferedInputStream as data source, please remember to use a buffer of size no less than RequestClientOptions.DEFAULT_STREAM_BUFFER_SIZE while initializing the BufferedInputStream. This is to ensure that the SDK can correctly mark and reset the stream with enough memory buffer during signing and retries.
    
    If versioning is enabled for the specified bucket, this operation will never overwrite an existing object at the same key, but instead will keep the existing object around as an older version until that version is explicitly deleted (see AmazonS3.deleteVersion(String, String, String).
    
    If versioning is not enabled, this operation will overwrite an existing object with the same key; Amazon S3 will store the last write request. Amazon S3 does not provide object locking. If Amazon S3 receives multiple write requests for the same object nearly simultaneously, all of the objects might be stored. However, a single object will be stored with the final write request.

    The specified bucket must already exist and the caller must have Permission.Write permission to the bucket to upload an object.
    
    Parameters:
    
    bucketName - The name of an existing bucket, to which you have Permission.Write permission.
    
    key - The key under which to store the specified file.
    
    input - The input stream containing the data to be uploaded to Amazon S3.
    
    metadata - Additional metadata instructing Amazon S3 how to handle the uploaded data (e.g. custom user metadata, hooks for specifying content type, etc.).
    
    Returns:
    
    A PutObjectResult object containing the information returned by Amazon S3 for the newly created object.
    
    Throws:
    
    SdkClientException - If any errors are encountered in the client while making the request or handling the response.

    Copies a source object to a new destination in Amazon S3.
    
    By default, all object metadata for the source object except server-side-encryption, storage-class and website-redirect-location are copied to the new destination object, unless new object metadata in the specified CopyObjectRequest is provided.
    
    The Amazon S3 Acccess Control List (ACL) is not copied to the new object. The new object will have the default Amazon S3 ACL, CannedAccessControlList.Private, unless one is explicitly provided in the specified CopyObjectRequest.
    
    To copy an object, the caller's account must have read access to the source object and write access to the destination bucket
    
    This method only exposes the basic options for copying an Amazon S3 object. Additional options are available by calling the AmazonS3Client.copyObject(CopyObjectRequest) method, including conditional constraints for copying objects, setting ACLs, overwriting object metadata, etc.
    
    If you are copying Amazon Web Services KMS-encrypted objects, you need to specify the correct region of the bucket on your client and configure Amazon Web Services Signature Version 4 for added security. For more information on how to do this, see http://docs.aws.amazon.com/AmazonS3/latest/dev/UsingAWSSDK.html# specify-signature-version
    
    Parameters:
    
    sourceBucketName - The name of the bucket containing the source object to copy.
    
    sourceKey - The key in the source bucket under which the source object is stored.
    
    destinationBucketName - The name of the bucket in which the new object will be created. This can be the same name as the source bucket's.
    
    destinationKey - The key in the destination bucket under which the new object will be created.
    
    Returns:
    
    A CopyObjectResult object containing the information returned by Amazon S3 for the newly created object.
    
    Throws:
    
    SdkClientException - If any errors are encountered in the client while making the request or handling the response.
    
    AmazonServiceException - If any errors occurred in Amazon S3 while processing the request.

    Copies a source object to a new destination in Amazon S3.
    
    By default, all object metadata for the source object except server-side-encryption, storage-class and website-redirect-location are copied to the new destination object, unless new object metadata in the specified CopyObjectRequest is provided.
    
    The Amazon S3 Acccess Control List (ACL) is not copied to the new object. The new object will have the default Amazon S3 ACL, CannedAccessControlList.Private, unless one is explicitly provided in the specified CopyObjectRequest.
    
    To copy an object, the caller's account must have read access to the source object and write access to the destination bucket.
    
    If constraints are specified in the CopyObjectRequest (e.g. CopyObjectRequest.setMatchingETagConstraints(List)) and are not satisfied when Amazon S3 receives the request, this method returns null. This method returns a non-null result under all other circumstances.
    
    This method exposes all the advanced options for copying an Amazon S3 object. For simple needs, use the AmazonS3Client.copyObject(String, String, String, String) method.
    
    If you are copying Amazon Web Services KMS-encrypted objects, you need to specify the correct region of the bucket on your client and configure Amazon Web Services Signature Version 4 for added security.

    Deletes a specific version of the specified object in the specified bucket. Once deleted, there is no method to restore or undelete an object version. This is the only way to permanently delete object versions that are protected by versioning.
    
    Deleting an object version is permanent and irreversible. It is a privileged operation that only the owner of the bucket containing the version can perform.
    
    Users can only delete a version of an object if versioning is enabled for the bucket. For more information about enabling versioning for a bucket, see AmazonS3.setBucketVersioningConfiguration(SetBucketVersioningConfigurationRequest).
    
    If attempting to delete an object that does not exist, Amazon S3 will return a success message instead of an error message.
    
    Parameters:
    
    bucketName - The name of the Amazon S3 bucket containing the object to delete.
    
    key - The key of the object to delete.

```
    Returns the versioning configuration for the specified bucket.
    
    A bucket's versioning configuration can be in one of three possible states:
    By default, new buckets are in the off state. Once versioning is enabled for a bucket the status can never be reverted to off.
    
    The versioning configuration of a bucket has different implications for each operation performed on that bucket or for objects within that bucket. For example, when versioning is enabled a PutObject operation creates a unique object version-id for the object being uploaded. The The PutObject API guarantees that, if versioning is enabled for a bucket at the time of the request, the new object can only be permanently deleted using a DeleteVersion operation. It can never be overwritten. Additionally, the PutObject API guarantees that, if versioning is enabled for a bucket the request, no other object will be overwritten by that request. Refer to the documentation sections for each API for information on how versioning status affects the semantics of that particular API.
    
    Amazon S3 is eventually consistent. It can take time for the versioning status of a bucket to be propagated throughout the system.
    Parameters:
    
    bucketName - The bucket whose versioning configuration will be retrieved.
    
    Returns:
    
    The bucket versioning configuration for the specified bucket.
    
    Throws:
    
    SdkClientException - If any errors are encountered in the client while making the request or handling the response.

    Sets the versioning configuration for the specified bucket.
    
    A bucket's versioning configuration can be in one of three possible states:
    By default, new buckets are in the off state. Once versioning is enabled for a bucket the status can never be reverted to off.
    
    Objects created before versioning was enabled or when versioning is suspended will be given the default null version ID (see Constants.NULL_VERSION_ID). Note that the null version ID is a valid version ID and is not the same as not having a version ID.

```
    Returns the website configuration for the specified bucket. Bucket website configuration allows you to host your static websites entirely out of Amazon S3. To host your website in Amazon S3, create a bucket, upload your files, and configure it as a website. Once your bucket has been configured as a website, you can access all your content via the Amazon S3 website endpoint. To ensure that the existing Amazon S3 REST API will continue to behave the same, regardless of whether or not your bucket has been configured to host a website, a new HTTP endpoint has been introduced where you can access your content. The bucket content you want to make available via the website must be publicly readable.
    For more information on how to host a website on Amazon S3, see: http://docs.amazonwebservices.com/AmazonS3/latest/dev/WebsiteHosting.html.
    This operation requires the S3:GetBucketWebsite permission. By default, only the bucket owner can read the bucket website configuration. However, bucket owners can allow other users to read the website configuration by writing a bucket policy granting them the S3:GetBucketWebsite permission.
    
    Parameters:
    
    bucketName - The name of the bucket whose website configuration is being retrieved.

    Returns the website configuration for the specified bucket. Bucket website configuration allows you to host your static websites entirely out of Amazon S3. To host your website in Amazon S3, create a bucket, upload your files, and configure it as a website. Once your bucket has been configured as a website, you can access all your content via the Amazon S3 website endpoint. To ensure that the existing Amazon S3 REST API will continue to behave the same, regardless of whether or not your bucket has been configured to host a website, a new HTTP endpoint has been introduced where you can access your content. The bucket content you want to make available via the website must be publicly readable.
    For more information on how to host a website on Amazon S3, see: http://docs.amazonwebservices.com/AmazonS3/latest/dev/WebsiteHosting. html.
    This operation requires the S3:GetBucketWebsite permission. By default, only the bucket owner can read the bucket website configuration. However, bucket owners can allow other users to read the website configuration by writing a bucket policy granting them the S3:GetBucketWebsite permission.
    
    Parameters:
    
    getBucketWebsiteConfigurationRequest - The request object for retrieving the bucket website configuration.
    
    Returns:
    
    The bucket website configuration for the specified bucket, otherwise null if there is no website configuration set for the specified bucket.
    
    Throws:
    
    SdkClientException - If any errors are encountered on the client while making the request or handling the response.

                         String key,
                         Date expiration)
                  throws SdkClientException
```
    Returns a pre-signed URL for accessing an Amazon S3 resource.
    
    Pre-signed URLs allow clients to form a URL for an Amazon S3 resource, and then sign it with the current Amazon Web Services security credentials. The pre-signed URL can be shared to other users, allowing access to the resource without providing an account's Amazon Web Services security credentials.
    
    Pre-signed URLs are useful in many situations where Amazon Web Services security credentials aren't available from the client that needs to make the actual request to Amazon S3.
    
    For example, an application may need remote users to upload files to the application owner's Amazon S3 bucket, but doesn't need to ship the Amazon Web Services security credentials with the application. A pre-signed URL to PUT an object into the owner's bucket can be generated from a remote location with the owner's Amazon Web Services security credentials, then the pre-signed URL can be passed to the end user's application to use.
    
    If you are generating presigned url for Amazon Web Services KMS-encrypted objects, you need to specify the correct region of the bucket on your client and configure Amazon Web Services Signature Version 4 for added security. For more information on how to do this, see http://docs.aws.amazon.com/AmazonS3/latest/dev/UsingAWSSDK.html# specify-signature-version
    
    Parameters:
    
    bucketName - The name of the bucket containing the desired object.
    
    key - The key in the specified bucket under which the desired object is stored.
    
    expiration - The time at which the returned pre-signed URL will expire.
    
    Returns:
    
    A pre-signed URL which expires at the specified time, and can be used to allow anyone to download the specified object from S3, without exposing the owner's Amazon Web Services secret access key.
    
    Throws:
    
    SdkClientException - If there were any problems pre-signing the request for the specified S3 object.

```
    Initiates a multipart upload and returns an InitiateMultipartUploadResult which contains an upload ID. This upload ID associates all the parts in the specific upload and is used in each of your subsequent AmazonS3.uploadPart(UploadPartRequest) requests. You also include this upload ID in the final request to either complete, or abort the multipart upload request.
    Note: After you initiate a multipart upload and upload one or more parts, you must either complete or abort the multipart upload in order to stop getting charged for storage of the uploaded parts. Once you complete or abort the multipart upload Amazon S3 will release the stored parts and stop charging you for their storage.
    
    If you are initiating a multipart upload for Amazon Web Services KMS-encrypted objects, you need to specify the correct region of the bucket on your client and configure Amazon Web Services Signature Version 4 for added security. For more information on how to do this, see http://docs.aws.amazon.com/AmazonS3/latest/dev/UsingAWSSDK.html# specify-signature-version

```
    Uploads a part in a multipart upload. You must initiate a multipart upload before you can upload any part.
    Your UploadPart request must include an upload ID, a part number and part size. The upload ID is the ID returned by Amazon S3 in response to your Initiate Multipart Upload request. Part number can be any number between 1 and 10,000, inclusive. A part number uniquely identifies a part and also defines its position within the object being uploaded. If you upload a new part using the same part number that was specified in uploading a previous part, the previously uploaded part is overwritten.
    For information about maximum and minimum part sizes and other multipart upload specifications, see Multipart upload limits in the Amazon S3 User Guide.
    
    To ensure data is not corrupted traversing the network, specify the Content-MD5 header in the Upload Part request. Amazon S3 checks the part data against the provided MD5 value. If they do not match, Amazon S3 returns an error.
    When you upload a part, the returned UploadPartResult contains an ETag property. You should record this ETag property value and the part number. After uploading all parts, you must send a CompleteMultipartUpload request. At that time Amazon S3 constructs a complete object by concatenating all the parts you uploaded, in ascending order based on the part numbers. The CompleteMultipartUpload request requires you to send all the part numbers and the corresponding ETag values.
    Note: After you initiate a multipart upload and upload one or more parts, you must either complete or abort the multipart upload in order to stop getting charged for storage of the uploaded parts. Once you complete or abort the multipart upload Amazon S3 will release the stored parts and stop charging you for their storage.
    
    If you are performing upload part for Amazon Web Services KMS-encrypted objects, you need to specify the correct region of the bucket on your client and configure Amazon Web Services Signature Version 4 for added security. For more information on how to do this, see http://docs.aws.amazon.com/AmazonS3/latest/dev/UsingAWSSDK.html# specify-signature-version
    
    When supplying an InputStream using UploadPartRequest.withInputStream(InputStream) or UploadPartRequest.setInputStream(InputStream), the stream will only be closed by the client if UploadPartRequest.isLastPart() is true. If this is not the last part, the stream will be left open.
    
    Specified by:
    
    uploadPart in interface S3DirectSpi
    
    Parameters:
    
    request - The UploadPartRequest object that specifies all the parameters of this operation.
    
    Returns:
    
    An UploadPartResult from Amazon S3 containing the part number and ETag of the new part.
    
    Throws:

```
    Lists the parts that have been uploaded for a specific multipart upload.
    This method must include the upload ID, returned by the AmazonS3.initiateMultipartUpload(InitiateMultipartUploadRequest) operation. This request returns a maximum of 1000 uploaded parts by default. You can restrict the number of parts returned by specifying the MaxParts property on the ListPartsRequest. If your multipart upload consists of more parts than allowed in the ListParts response, the response returns a IsTruncated field with value true, and a NextPartNumberMarker property. In subsequent ListParts request you can include the PartNumberMarker property and set its value to the NextPartNumberMarker property value from the previous response.
    
    Parameters:
    
    request - The ListPartsRequest object that specifies all the parameters of this operation.
    
    Returns:
    
    Returns a PartListing from Amazon S3.

    Aborts a multipart upload. After a multipart upload is aborted, no additional parts can be uploaded using that upload ID. The storage consumed by any previously uploaded parts will be freed. However, if any part uploads are currently in progress, those part uploads may or may not succeed. As a result, it may be necessary to abort a given multipart upload multiple times in order to completely free all storage consumed by all parts.

```
    Completes a multipart upload by assembling previously uploaded parts.
    
    You first initiate the multipart upload and then upload all parts using the UploadPart operation. After successfully uploading all relevant parts of an upload, you call this action to complete the upload. Upon receiving this request, Amazon S3 concatenates all the parts in ascending order by part number to create a new object. In the Complete Multipart Upload request, you must provide the parts list. You must ensure that the parts list is complete. This action concatenates the parts that you provide in the list. For each part in the list, you must provide the part number and the ETag value, returned after that part was uploaded.
    
    Processing of a Complete Multipart Upload request could take several minutes to complete. After Amazon S3 begins processing the request, it sends an HTTP response header that specifies a 200 OK response. While processing is in progress, Amazon S3 periodically sends white space characters to keep the connection from timing out. A request could fail after the initial 200 OK response has been sent. This means that a 200 OK response can contain either a success or an error. If you call the S3 API directly, make sure to design your application to parse the contents of the response and handle it appropriately. If you use Amazon Web Services SDKs, SDKs handle this condition. The SDKs detect the embedded error and apply error handling per your configuration settings (including automatically retrying the request as appropriate). If the condition persists, the SDKs throws an exception (or, for the SDKs that don't use exceptions, they return the error).
    
    Note that if CompleteMultipartUpload fails, applications should be prepared to retry the failed requests. For more information, see Amazon S3 Error Best Practices.
    
    You cannot use Content-Type: application/x-www-form-urlencoded with Complete Multipart Upload requests. Also, if you do not provide a Content-Type header, CompleteMultipartUpload returns a 200 OK response.

```
    Lists in-progress multipart uploads. An in-progress multipart upload is a multipart upload that has been initiated, using the InitiateMultipartUpload request, but has not yet been completed or aborted.
    This operation returns at most 1,000 multipart uploads in the response by default. The number of multipart uploads can be further limited using the MaxUploads property on the request parameter. If there are additional multipart uploads that satisfy the list criteria, the response will contain an IsTruncated property with the value set to true. To list the additional multipart uploads use the KeyMarker and UploadIdMarker properties on the request parameters.
    
    Parameters:
    
    request - The ListMultipartUploadsRequest object that specifies all the parameters of this operation.
    
    Returns:
    
    A MultipartUploadListing from Amazon S3.
    
    Throws:
    
    SdkClientException - If any errors are encountered in the client while making the request or handling the response.
    
    AmazonServiceException - If any errors occurred in Amazon S3 while processing the request.

  - getCachedResponseMetadata
```
S3ResponseMetadata getCachedResponseMetadata(AmazonWebServiceRequest request)
```
    Gets additional metadata for a previously executed successful request. The returned metadata is typically used for debugging issues when a service isn't acting as expected. This data isn't considered part of the result data returned by an operation; as so, it's available through this separate diagnostic interface.
    Response metadata is only cached for a limited period of time. Use this method to retrieve the response metadata as soon as possible after executing a request.
    
    Parameters:
    
    request - The originally executed request.
    
    Returns:
    
    The response metadata for the specified request, or null if none is available.
  - restoreObject
```
void restoreObject(RestoreObjectRequest request)
            throws AmazonServiceException
```
    Restore an object, which was transitioned to Amazon Glacier from Amazon S3 when it was expired, into Amazon S3 again. This copy is by nature temporary and is always stored as RRS in Amazon S3. The customer will be able to set / re-adjust the lifetime of this copy. By re-adjust we mean the customer can call this API to shorten or extend the lifetime of the copy. Note the request will only be accepted when there is no ongoing restore request. One needs to have the new s3:RestoreObject permission to perform this operation.
    
    Parameters:
    
    request - The request object containing all the options for restoring an Amazon S3 object.
    
    Throws:
    
    AmazonServiceException - If any errors occurred in Amazon S3 while processing the request.

    Creates a replication configuration or replaces an existing one. For more information, see Replication in the Amazon S3 User Guide.
    
    Specify the replication configuration in the request body. In the replication configuration, you provide the name of the destination bucket or buckets where you want Amazon S3 to replicate objects, the IAM role that Amazon S3 can assume to replicate objects on your behalf, and other relevant information.
    
    A replication configuration must include at least one rule, and can contain a maximum of 1,000. Each rule identifies a subset of objects to replicate by filtering the objects in the source bucket. To choose additional subsets of objects to replicate, add a rule for each subset.
    
    To specify a subset of the objects in the source bucket to apply a replication rule to, add the Filter element as a child of the Rule element. You can filter objects based on an object key prefix, one or more object tags, or both. When you add the Filter element in the configuration, you must also add the following elements: DeleteMarkerReplication, Status, and Priority.
    
    If you are using an earlier version of the replication configuration, Amazon S3 handles replication of delete markers differently. For more information, see Backward Compatibility.
    
    For information about enabling versioning on a bucket, see Using Versioning.
    
    Handling Replication of Encrypted Objects
    
    By default, Amazon S3 doesn't replicate objects that are stored at rest using server-side encryption with CMKs stored in Amazon Web Services KMS. To replicate Amazon Web Services KMS-encrypted objects, add the following: SourceSelectionCriteria, SseKmsEncryptedObjects, Status, EncryptionConfiguration, and ReplicaKmsKeyID. For information about replication configuration, see Replicating Objects Created with SSE Using CMKs stored in Amazon Web Services KMS.

    Permissions
    
    To create a PutBucketReplication request, you must have s3:PutReplicationConfiguration permissions for the bucket.
    
    By default, a resource owner, in this case the Amazon Web Services account that created the bucket, can perform this operation. The resource owner can also grant others permissions to perform the operation. For more information about permissions, see Specifying Permissions in a Policy and Managing Access Permissions to Your Amazon S3 Resources.
    
    To perform this operation, the user or role performing the action must have the iam:PassRole permission.

  - download
```
PresignedUrlDownloadResult download(PresignedUrlDownloadRequest presignedUrlDownloadRequest)
```
    Gets the object stored in Amazon S3 using a presigned url.
    The result contains S3Object representing the downloaded object. Be extremely careful when using this method; the returned Amazon S3 object contains a direct stream of data from the HTTP connection. The underlying HTTP connection cannot be reused until the user finishes reading the data and closes the stream. Also note that if not all data is read from the stream then the SDK will abort the underlying connection, this may have a negative impact on performance. Therefore:
    - Use the data from the input stream in Amazon S3 object as soon as possible
    - Read all data from the stream (use PresignedUrlDownloadRequest.setRange(long, long) to request only the bytes you need)
    - Close the input stream in Amazon S3 object as soon as possible
    If these rules are not followed, the client can run out of resources by allocating too many open, but unused, HTTP connections.
    Parameters:
    
    presignedUrlDownloadRequest - The request object to download the object.
    
    Returns:
    
    result shape containing the downloaded stream
    
    Throws:
    
    SdkClientException - If any errors are encountered in the client while making the request or handling the response.
    
    AmazonServiceException - If any errors occurred in Amazon S3 while processing the request.
  - download
```
void download(PresignedUrlDownloadRequest presignedUrlDownloadRequest,
              File destinationFile)
```
    Gets the object stored in Amazon S3 using a presigned url.
    The result contains S3Object representing the downloaded object. Be extremely careful when using this method; the returned Amazon S3 object contains a direct stream of data from the HTTP connection. The underlying HTTP connection cannot be reused until the user finishes reading the data and closes the stream. Also note that if not all data is read from the stream then the SDK will abort the underlying connection, this may have a negative impact on performance. Therefore:
    - Use the data from the input stream in Amazon S3 object as soon as possible
    - Read all data from the stream (use PresignedUrlDownloadRequest.setRange(long, long) to request only the bytes you need)
    - Close the input stream in Amazon S3 object as soon as possible
    If these rules are not followed, the client can run out of resources by allocating too many open, but unused, HTTP connections.
    Parameters:
    
    presignedUrlDownloadRequest - The request object to download the object.
    
    destinationFile - Indicates the file (which might already exist) where to save the object content being downloading from Amazon S3.
    
    Throws:
    
    SdkClientException - If any errors are encountered in the client while making the request or handling the response.
    
    AmazonServiceException - If any errors occurred in Amazon S3 while processing the request.
  - upload
```
PresignedUrlUploadResult upload(PresignedUrlUploadRequest presignedUrlUploadRequest)
```
    Uploads a new object into S3 using the given presigned url.
    Depending on whether a file or input stream is being uploaded, this request has slightly different behavior.
    
    When uploading a file:
    - The client automatically computes a checksum of the file. Amazon S3 uses checksums to validate the data in each file.
    - Using the file extension, Amazon S3 attempts to determine the correct content type and content disposition to use for the object with some exceptions. See below.
    - If the given presigned url is created using SigV2 signer and content type is not provided, then SDK will not attempt to determine the content type and instead sends an empty string for content type. This is because content type is signed header in SigV2 and so the content type can only be sent if it is used in creating presigned url.
    - If the given presigned url is created using SigV4 signer, then SDK attempts to determine the correct content type and sends it with the request if not provided. Note that this only works if you have not used content type while creating the presigned url. If you have used content type while creating the url, then you should set the same content type while making this API call through PresignedUrlUploadRequest.setMetadata(ObjectMetadata) or AmazonWebServiceRequest.putCustomRequestHeader(String, String)
    When uploading directly from an input stream, content length must be specified before data can be uploaded to Amazon S3. If not provided, the library will have to buffer the contents of the input stream in order to calculate it. Amazon S3 explicitly requires that the content length be sent in the request headers before any of the data is sent.

Parameters:: presignedUrlUploadRequest - The request object containing all the parameters to upload a new object to Amazon S3.
Returns:: A PresignedUrlUploadResult object containing the information returned by Amazon S3 for the newly created object.
Throws:: SdkClientException - If any errors are encountered in the client while making the request or handling the response.; AmazonServiceException - If any errors occurred in Amazon S3 while processing the request.

shutdown
```
void shutdown()
```
Shuts down this client object, releasing any resources that might be held open. This is an optional method, and callers are not expected to call it, but can if they want to explicitly release any open resources. Once a client has been shutdown, it should not be used to make any more requests.

getRegion
```
Region getRegion()
```
Returns the region with which the client is configured.

Returns:

The region this client will communicate with.

getRegionName
```
String getRegionName()
```
Returns a string representation of the region with which this client is configured

Returns:

String value representing the region this client will communicate with

getUrl
```
URL getUrl(String bucketName,
           String key)
```
Returns an URL for the object stored in the specified bucket and key.
If the object identified by the given bucket and key has public read permissions (ex: CannedAccessControlList.PublicRead), then this URL can be directly accessed to retrieve the object's data.

Parameters:

bucketName - The name of the bucket containing the object whose URL is being requested.

key - The key under which the object whose URL is being requested is stored.

Returns:

A unique URL for the object stored in the specified bucket and key.
