Interface SubProgressObserver

All Superinterfaces:

CancelObserver, ProgressObserver

@Beta
public interface SubProgressObserver
extends ProgressObserver

Observer for reporting the progress of subtasks.

This observer is intended to follow the executions of subtasks (using ProgressObserver.subTask(java.lang.String, long)). The only additional constraint is that the explicit signalling of finisging the work (using done() is required; usually by the host task.

Please note that this interface is marked with @Beta annotation, so it can be subject of incompatible changes or removal in any of the later releases.
