process

protected IteratingCallback.Action process()
                                    throws java.lang.Exception

Description copied from class: IteratingCallback

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

Implementations must start 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:

java.lang.Exception

process

private void process(java.nio.ByteBuffer content,
                     Callback callback,
                     boolean finished)
              throws java.io.IOException

Throws:

java.io.IOException

onCompleteFailure

protected void onCompleteFailure(java.lang.Throwable x)

Description copied from class: IteratingCallback

Invoked when the overall task has completed with a failure.

Overrides:

onCompleteFailure in class IteratingCallback

Parameters:

x - the throwable to indicate cause of failure
