类 UploadMonitor

java.lang.Object

com.qcloud.cos.transfer.UploadMonitor

所有已实现的接口:

TransferMonitor, Callable<UploadResult>

public class UploadMonitor
extends Object
implements 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()

方法详细资料

getFuture

public Future<UploadResult> getFuture()

从接口复制的说明: 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.

指定者:

getFuture 在接口中 TransferMonitor

isDone

public boolean isDone()

从接口复制的说明: TransferMonitor

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

指定者:

isDone 在接口中 TransferMonitor

create

public static UploadMonitor create(TransferManager manager,
                   UploadImpl transfer,
                   ExecutorService threadPool,
                   UploadCallable multipartUploadCallable,
                   PutObjectRequest putObjectRequest,
                   ProgressListenerChain progressListenerChain)

Constructs a new upload watcher and then immediately submits it to the thread pool.

参数:

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

call

public UploadResult call()
                  throws Exception

指定者:

call 在接口中 Callable<UploadResult>

抛出:

Exception
