Method Summary

void	onMaxNumberOfThreadsEvent(AbstractThreadPool threadPool, int maxNumberOfThreads) This event may be fired when the AbstractThreadPool implementation has allocated and is managing a number of threads equal to the maximum limit of the pool.
void	onTaskCompleteEvent(AbstractThreadPool threadPool, java.lang.Runnable task) This event may be fired when a dequeued task has completed processing.
void	onTaskDequeueEvent(AbstractThreadPool threadPool, java.lang.Runnable task) This event may be fired when a task has been pulled from the queue and is about to be processed.
void	onTaskQueueEvent(AbstractThreadPool threadPool, java.lang.Runnable task) This event may be fired when a task has been queued for processing.
void	onTaskQueueOverflowEvent(AbstractThreadPool threadPool) This event may be fired when the task queue of the AbstractThreadPool implementation has exceeded its configured size.
void	onThreadAllocateEvent(AbstractThreadPool threadPool, java.lang.Thread thread) This event may be fired when an AbstractThreadPool implementation allocates a new managed Thread.
void	onThreadPoolStartEvent(AbstractThreadPool threadPool) This event may be fired when an AbstractThreadPool implementation starts running.
void	onThreadPoolStopEvent(AbstractThreadPool threadPool) This event may be fired when an AbstractThreadPool implementation stops.
void	onThreadReleaseEvent(AbstractThreadPool threadPool, java.lang.Thread thread) This event may be fired when a thread will no longer be managed by the AbstractThreadPool implementation.
