Method Details

offer

public boolean offer(ByteBuffer content,
 Callback callback)

process

protected IteratingCallback.Action process()
                                    throws Throwable

Description copied from class: IteratingCallback

Method called by IteratingCallback.iterate() to process the asynchronous sub-task.

Implementations must initiate the asynchronous execution of the sub-task (if any) and return an appropriate action:

• IteratingCallback.Action.IDLE when no sub tasks are available for execution but the overall job is not completed yet
• IteratingCallback.Action.SCHEDULED when the sub task asynchronous execution has been started
• IteratingCallback.Action.SUCCEEDED when the overall job is completed

Specified by:

process in class IteratingCallback

Returns:

the appropriate Action

Throws:

Throwable - if the sub-task processing throws

onSuccess

protected void onSuccess()

Description copied from class: IteratingCallback

Invoked when one task has completed successfully, either by the caller thread or by the processing thread. This invocation is always serialized w.r.t the execution of IteratingCallback.process().

This method is not invoked when a call to IteratingCallback.abort(Throwable) is made before the IteratingCallback.succeeded() callback happens.

Overrides:

onSuccess in class IteratingCallback

onCompleteFailure

protected void onCompleteFailure(Throwable failure)

Description copied from class: IteratingCallback

Invoked when the overall task has completed with a failure.

Overrides:

onCompleteFailure in class IteratingCallback

Parameters:

failure - the throwable to indicate cause of failure

• IteratingCallback.onCompleteSuccess()

onWritePossible

public void onWritePossible()

Specified by:

onWritePossible in interface javax.servlet.WriteListener

onError

public void onError(Throwable failure)

Specified by:

onError in interface javax.servlet.WriteListener
