public class TransferManager extends Object
TransferManager provides a simple API for uploading content to
Amazon S3, and makes extensive use of Amazon S3 multipart uploads to achieve
enhanced throughput, performance and reliability.
When possible, TransferManager attempts to use multiple threads
to upload multiple parts of a single upload at once. When dealing with large
content sizes and high bandwidth, this can have a significant increase on
throughput.
TransferManager is responsible for managing resources such as
connections and threads; share a single instance of
TransferManager whenever possible. TransferManager,
like all the client classes in the Amazon Web Services SDK for Java, is thread safe. Call
TransferManager.shutdownNow() to release the resources once the
transfer is complete.
Using TransferManager to upload objects to Amazon S3 is easy:
DefaultAWSCredentialsProviderChain credentialProviderChain = new DefaultAWSCredentialsProviderChain();
TransferManager tx = new TransferManager(
credentialProviderChain.getCredentials());
Upload myUpload = tx.upload(myBucket, myFile.getName(), myFile);
// You can poll your transfer's status to check its progress
if (myUpload.isDone() == false) {
System.out.println("Transfer: " + myUpload.getDescription());
System.out.println(" - State: " + myUpload.getState());
System.out.println(" - Progress: "
+ myUpload.getProgress().getBytesTransferred());
}
// Transfers also allow you to set a <code>ProgressListener</code> to receive
// asynchronous notifications about your transfer's progress.
myUpload.addProgressListener(myProgressListener);
// Or you can block the current thread and wait for your transfer to
// to complete. If the transfer fails, this method will throw an
// AmazonClientException or AmazonServiceException detailing the reason.
myUpload.waitForCompletion();
// After the upload is complete, call shutdownNow to release the resources.
tx.shutdownNow();
Transfers can be paused and resumed at a later time. It can also survive JVM crash, provided the information that is required to resume the transfer is given as input to the resume operation. For more information on pause and resume,

public Upload upload(String bucketName, String key, InputStream input, ObjectMetadata objectMetadata) throws AmazonServiceException, AmazonClientException
Schedules a new transfer to upload data to Amazon S3. This method is non-blocking and returns immediately (i.e. before the upload has finished).
When uploading options from a stream, callers must supply the size of
options in the stream through the content length field in the
ObjectMetadata parameter.
If no content length is specified for the input
stream, then TransferManager will attempt to buffer all the stream
contents in memory and upload the options as a traditional, single part
upload. Because the entire stream contents must be buffered in memory,
this can be very expensive, and should be avoided whenever possible.

transfer, add listeners for progress events, and wait for the upload to

If resources are available, the upload will begin immediately. Otherwise, the upload is scheduled and started as soon as resources become available.

Aborts any multipart uploads that were initiated before the specified date.
This method is useful for cleaning up any interrupted multipart uploads.
TransferManager attempts to abort any failed uploads,
but in some cases this may not be possible, such as if network connectivity
is completely lost.

Callers should also remember that uploaded parts from an interrupted
upload may not always be automatically cleaned up, but callers can use
TransferManager.abortMultipartUploads(String, Date) to clean up any upload
parts.
shutDownS3Client - Whether to shut down the underlying Amazon S3 client.public static <X extends AmazonWebServiceRequest> X appendSingleObjectUserAgent(X request)

public Copy copy(String sourceBucketName, String sourceKey, String destinationBucketName, String destinationKey) throws AmazonServiceException, AmazonClientException
Schedules a new transfer to copy data from one Amazon S3 location to another Amazon S3 location. This method is non-blocking and returns immediately (before the copy has finished).
TransferManager doesn't support copying of encrypted objects
whose encryption materials are stored in an instruction file.
Use the returned Copy object to check if the copy is
complete.
If resources are available, the copy request will begin immediately. Otherwise, the copy is scheduled and started as soon as resources become available.
Note: If the TransferManager is created with a regional S3 client and
the source & destination buckets are in different regions, use the
TransferManager.copy(CopyObjectRequest, AmazonS3, TransferStateChangeListener) method.
