Constructor Detail

Task

public Task(BlockDefinition blockDefinition,
            long timeout)

Constructor.

Parameters:

blockDefinition - Progress block for which timeout is set.

timeout - Number of seconds which will be set as a timeout.

Task

public Task(StopAfterTimer.Task existingTask)

Copy constructor.

Parameters:

existingTask - Canceled task from which a new timer task will be created.

Method Detail

run

public void run()

Method responsible for stopping the thread corresponding to the session and subsequent cleanup of the children task's.

Specified by:

run in interface java.lang.Runnable

Specified by:

run in class java.util.TimerTask

finished

public void finished()

Called by the transaction manager just before a block closes. This is our hook to update the state of semaphore and timer task related to current block.

Specified by:

finished in interface Finalizable

deleted

public void deleted()

Provides a notification that the external program scope in which the object is registered is is being deleted and the object's reference will be lost after this method is called.

Specified by:

deleted in interface Finalizable

iterate

public void iterate()

Called by the transaction manager after each iteration of a repeating block. Cancel the timer task for the previous iteration. Relinquishes the semaphore and starts a new timer task for next iteration.

Specified by:

iterate in interface Finalizable

retry

public void retry()

Called by the transaction manager before a block is retried after an error. Cancel the timer task for the previous iteration. Relinquishes the semaphore and starts a new timer task for next iteration.

Specified by:

retry in interface Finalizable
