ThreadPoolProbe.Adapter
ThreadPoolProbe adapter that provides no-op implementations for
all interface methods allowing easy extension by the developer. |
Modifier and Type | Method and 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,
Runnable task)
This event may be fired when a dequeued task has been canceled.
|
void |
onTaskCompleteEvent(AbstractThreadPool threadPool,
Runnable task)
This event may be fired when a dequeued task has completed processing.
|
void |
onTaskDequeueEvent(AbstractThreadPool threadPool,
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,
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,
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,
Thread thread)
This event may be fired when a thread will no longer be managed by the
AbstractThreadPool implementation. |
void onThreadPoolStartEvent(AbstractThreadPool threadPool)
This event may be fired when an AbstractThreadPool
implementation
starts running.
