Method Detail

reset

public void reset()

Description copied from class: ARuntime

The workerpool enters a transitional period when reset() is issued. It waits for all the working thread to either finishes the job or goes into sleep. After all the threads finish jobs, it releases all the threads by kill()ing them.

CAUTION: 1. This method is better be executed by a thread that is not created from this worker pool, unless you know what you're doing. 2. Current implementation does not work if a thread executes indefinitely.

Overrides:

reset in class ARuntime

systemBecomesIdle

protected void systemBecomesIdle(AWorkerThread exe_)

Description copied from class: ARuntime

Subclasses should override this method to handle the event when all workerthreads in the system are either waiting or idle but there are still tasks in the waiting queue.

Overrides:

systemBecomesIdle in class ARuntime

Parameters:

exe_ - current thread, requests waiting and leads the system to the idle state.

_getTime

protected double _getTime()

Description copied from class: ARuntime

Asynchronized version of getTime(), for diagnosis. Subclasses should override this method to provide its own time mapping function.

Overrides:

_getTime in class ARuntime

t_info

protected java.lang.String t_info(java.lang.String prefix_)

Overrides:

t_info in class ARuntime
