Constructor Detail

TaskSignaledObserver

public TaskSignaledObserver()

TaskSignalObserver. Extends TaskObserverRoot and implements TaskObserver.Signaled Provides functionality for the Signaled Frysk Core observer in the UI.

TaskSignaledObserver

protected TaskSignaledObserver(TaskSignaledObserver other)

TaskSignalObserver. Extends TaskObserverRoot and implements TaskObserver.Signaled Provides functionality for the Signaled Frysk Core observer in the UI. Produces a new TaskSignalOberser from the observer passed as a parameter. This is used in cloning the observer.

Method Detail

apply

public void apply(Task task)

Specified by:

apply in class TaskObserverRoot

unapply

public void unapply(Task task)

Specified by:

unapply in class TaskObserverRoot

updateSignaled

public Action updateSignaled(Task task,
                             Signal signal)

Description copied from interface: TaskObserver.Signaled

The SIGNAL is pending delivery to the task. Return Action.BLOCK to block the task's further execution. XXX: This gets weird. At present and in theory, a client wanting to discard a signal would need to sequence the following: tell the task to scrub discard the signal; tell the task to remove this observer from the set of blockers; return Action.BLOCK so that this task is added to the set of blockers. Perhaps it would be better to always add an observer to the blocker pool and then require explict removal.
