类 ProgressListenerChain

java.lang.Object

com.qcloud.cos.event.ProgressListenerChain

所有已实现的接口:

DeliveryMode, ProgressListener

直接已知子类:

COSProgressListenerChain

public class ProgressListenerChain
extends Object
implements ProgressListener, DeliveryMode

An implementation of ProgressListener interface that delegates progressChanged callback to multiple listeners. It also takes an optional ProgressEventFilter to filter incoming events before passing them to the listeners.

构造器详细资料

ProgressListenerChain

public ProgressListenerChain(ProgressListener... listeners)

Create a listener chain that directly passes all the progress events to the specified listeners.

ProgressListenerChain

public ProgressListenerChain(ProgressEventFilter progressEventFilter,
                     ProgressListener... listeners)

Create a listener chain with a ProgressEventFilter.

方法详细资料

addProgressListener

public void addProgressListener(ProgressListener listener)

removeProgressListener

public void removeProgressListener(ProgressListener listener)

getListeners

protected List<ProgressListener> getListeners()

Returns the listeners associated with this listener chain.

progressChanged

public void progressChanged(ProgressEvent progressEvent)

从接口复制的说明: ProgressListener

Called when progress has changed, such as additional bytes transferred, transfer failed, etc. The execution of the callback of this listener is managed by SDKProgressPublisher. Implementation of this interface should never block.

If the implementation follows the best practice and doesn't block, it should then extends from SyncProgressListener.

Note any exception thrown by the listener will get ignored. Should there be need to capture any such exception, you may consider wrapping the listener with ProgressListener.ExceptionReporter.wrap(ProgressListener).

指定者:

progressChanged 在接口中 ProgressListener

参数:

progressEvent - The event describing the progress change.

SDKProgressPublisher, ProgressListener.ExceptionReporter

isSyncCallSafe

public boolean isSyncCallSafe()

从接口复制的说明: DeliveryMode

Returns true if it is safe to make a synchronous callback to the implementing listener without the risk of incurring undue latency; false otherwise.

指定者:

isSyncCallSafe 在接口中 DeliveryMode
