addStateChangeListener

public void addStateChangeListener(StateMachine.StateChangeListener<TaskStatus> stateChangeListener)

Description copied from interface: RemoteTask

Listener is always notified asynchronously using a dedicated notification thread pool so, care should be taken to avoid leaking this when adding a listener in a constructor. Additionally, it is possible notifications are observed out of order due to the asynchronous execution.

Specified by:

addStateChangeListener in interface RemoteTask

addFinalTaskInfoListener

public void addFinalTaskInfoListener(StateMachine.StateChangeListener<TaskInfo> stateChangeListener)

Description copied from interface: RemoteTask

Add a listener for the final task info. This notification is guaranteed to be fired only once. Listener is always notified asynchronously using a dedicated notification thread pool so, care should be taken to avoid leaking this when adding a listener in a constructor. Additionally, it is possible notifications are observed out of order due to the asynchronous execution.

Specified by:

addFinalTaskInfoListener in interface RemoteTask
