Method Detail

publishProgress

public static Future<?> publishProgress(ProgressListener listener,
                        ProgressEventType type)

Used to deliver a progress event to the given listener.

Returns:

the future of a submitted task; or null if the delivery is synchronous with no future task involved. Note a listener should never block, and therefore returning null is the typical case.

publishRequestContentLength

public static Future<?> publishRequestContentLength(ProgressListener listener,
                                    long bytes)

Convenient method to publish a request content length event to the given listener.

Parameters:

listener - must not be null or else the publication will be skipped

bytes - must be non-negative or else the publication will be skipped

publishResponseContentLength

public static Future<?> publishResponseContentLength(ProgressListener listener,
                                     long bytes)

Convenient method to publish a response content length event to the given listener.

Parameters:

listener - must not be null or else the publication will be skipped

bytes - must be non-negative or else the publication will be skipped

publishRequestBytesTransferred

public static Future<?> publishRequestBytesTransferred(ProgressListener listener,
                                       long bytes)

Convenient method to publish a request byte transfer event to the given listener.

Parameters:

listener - must not be null or else the publication will be skipped

bytes - must be non-negative or else the publication will be skipped

publishResponseBytesTransferred

public static Future<?> publishResponseBytesTransferred(ProgressListener listener,
                                        long bytes)

Convenient method to publish a response byte transfer event to the given listener.

Parameters:

listener - must not be null or else the publication will be skipped

bytes - must be non-negative or else the publication will be skipped

publishRequestReset

public static Future<?> publishRequestReset(ProgressListener listener,
                            long bytesReset)

Convenient method to publish a request reset event to the given listener.

Parameters:

listener - must not be null or else the publication will be skipped

bytesReset - must be non-negative or else the publication will be skipped

publishResponseReset

public static Future<?> publishResponseReset(ProgressListener listener,
                             long bytesReset)

Convenient method to publish a response reset event to the given listener.

publishResponseBytesDiscarded

public static Future<?> publishResponseBytesDiscarded(ProgressListener listener,
                                      long bytesDiscarded)

Convenient method to publish a response bytes discard event to the given listener.

getExecutorService

protected static ExecutorService getExecutorService()

Returns the executor service used for performing the callbacks.

setLatestFutureTask

protected static Future<?> setLatestFutureTask(Future<?> f)

waitTillCompletion

@Deprecated
public static void waitTillCompletion()
                               throws InterruptedException,
                                      ExecutionException

Deprecated.

For internal testing and backward compatibility only. This method blocks until all the submitted callbacks are executed. Listeners should never block so this method should never be used.

Throws:

InterruptedException

ExecutionException
