TransferMonitor, java.util.concurrent.Callable<UploadResult>

public class UploadMonitor
extends java.lang.Object
implements java.util.concurrent.Callable<UploadResult>, TransferMonitor

Manages an upload by periodically checking to see if the upload is done, and returning a result if so. Otherwise, schedules a copy of itself to be run in the future and returns null. When waiting on the result of this class via a Future object, clients must call isDone() and getFuture()

UploadMonitor

public UploadMonitor(TransferManager manager,
             UploadImpl transfer,
             java.util.concurrent.ExecutorService threadPool,
             UploadCallable multipartUploadCallable,
             PutObjectRequest putObjectRequest,
             ProgressListenerChain progressListenerChain)

Constructs a new upload watcher, which immediately submits itself to the thread pool.

パラメータ:

manager - The TransferManager that owns this upload.

transfer - The transfer being processed.

threadPool - The ExecutorService to which we should submit new tasks.

multipartUploadCallable - The callable responsible for processing the upload asynchronously

putObjectRequest - The original putObject request

progressListenerChain - A chain of listeners that wish to be notified of upload progress

メソッドの詳細

getFuture

public java.util.concurrent.Future<UploadResult> getFuture()

インタフェースからコピーされた説明: TransferMonitor

Returns a Future to wait on. Calling get() on this future will block while the transfer progress is checked, but its return does not guarantee the transfer is complete. Call isDone() to check for completion. Repeated calls to getFuture() can return different objects.

定義:

getFuture インタフェース内 TransferMonitor

isDone

public boolean isDone()

インタフェースからコピーされた説明: TransferMonitor

Returns whether the transfer is completed. A failure or cancellation counts as completion as well; to gather any exceptions thrown, call getFuture().get()

定義:

isDone インタフェース内 TransferMonitor

setTimedThreadPool

public void setTimedThreadPool(java.util.concurrent.ScheduledExecutorService timedThreadPool)

call

public UploadResult call()
                  throws java.lang.Exception

定義:

call インタフェース内 java.util.concurrent.Callable<UploadResult>

例外:

java.lang.Exception
