Class CopyCallable

java.lang.Object

com.ibm.cloud.objectstorage.services.s3.transfer.internal.CopyCallable

All Implemented Interfaces:

Callable<CopyResult>

public class CopyCallable
extends Object
implements Callable<CopyResult>

An implementation of the Callable interface that helps TransferManager in carrying out the copy requests. The call method checks if multi-part copy request can be carried out on the Amazon S3 object. This is done by checking the size of the Amazon S3 object being copied.

If the size of the object is greater than the preferred size limit, then copy operation is carried out as multi part copy requests to the server.

If the size of the object is less than the preferred size limit, the copy operation is carried out in a single request where the Amazon S3 object is transferred as one chunk from the source bucket to the destination bucket.
