Modifier and Type	Method	Description
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	onTaskCancelEvent(AbstractThreadPool threadPool, java.lang.Runnable task)	This event may be fired when a dequeued task has been canceled.
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.

Method Detail

onThreadPoolStartEvent

public void onThreadPoolStartEvent(AbstractThreadPool threadPool)

This event may be fired when an AbstractThreadPool implementation starts running.

Specified by:

onThreadPoolStartEvent in interface ThreadPoolProbe

Parameters:

threadPool - the AbstractThreadPool being monitored

onThreadPoolStopEvent

public void onThreadPoolStopEvent(AbstractThreadPool threadPool)

This event may be fired when an AbstractThreadPool implementation stops.

Specified by:

onThreadPoolStopEvent in interface ThreadPoolProbe

Parameters:

threadPool - the AbstractThreadPool being monitored

onThreadAllocateEvent

public void onThreadAllocateEvent(AbstractThreadPool threadPool,
                                  java.lang.Thread thread)

This event may be fired when an AbstractThreadPool implementation allocates a new managed Thread.

Specified by:

onThreadAllocateEvent in interface ThreadPoolProbe

Parameters:

threadPool - the AbstractThreadPool being monitored

thread - the thread that has been allocated

onThreadReleaseEvent

public 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.

Specified by:

onThreadReleaseEvent in interface ThreadPoolProbe

Parameters:

threadPool - the AbstractThreadPool being monitored

thread - the thread that is no longer being managed by the AbstractThreadPool

onMaxNumberOfThreadsEvent

public 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.

Specified by:

onMaxNumberOfThreadsEvent in interface ThreadPoolProbe

Parameters:

threadPool - the AbstractThreadPool being monitored

maxNumberOfThreads - the maximum number of threads allowed in the AbstractThreadPool

onTaskQueueEvent

public void onTaskQueueEvent(AbstractThreadPool threadPool,
                             java.lang.Runnable task)

This event may be fired when a task has been queued for processing.

Specified by:

onTaskQueueEvent in interface ThreadPoolProbe

Parameters:

threadPool - the AbstractThreadPool being monitored

task - a unit of work to be processed

onTaskDequeueEvent

public 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.

Specified by:

onTaskDequeueEvent in interface ThreadPoolProbe

Parameters:

threadPool - the AbstractThreadPool being monitored

task - a unit of work that is about to be processed.

onTaskCancelEvent

public void onTaskCancelEvent(AbstractThreadPool threadPool,
                              java.lang.Runnable task)

This event may be fired when a dequeued task has been canceled.

This event can occur during shutdownNow() invocation, where tasks are getting pulled out of thread pool queue and returned as the result of shutdownNow() method call.

Specified by:

onTaskCancelEvent in interface ThreadPoolProbe

Parameters:

threadPool - the AbstractThreadPool being monitored

task - a unit of work that has been canceled

onTaskCompleteEvent

public void onTaskCompleteEvent(AbstractThreadPool threadPool,
                                java.lang.Runnable task)

This event may be fired when a dequeued task has completed processing.

Specified by:

onTaskCompleteEvent in interface ThreadPoolProbe

Parameters:

threadPool - the AbstractThreadPool being monitored

task - the unit of work that has completed processing

This event may be fired when the task queue of the AbstractThreadPool implementation has exceeded its configured size.

Specified by:

onTaskQueueOverflowEvent in interface ThreadPoolProbe

Parameters:

threadPool - the AbstractThreadPool being monitored
