Method Detail

execute

public void execute(Runnable task)

Description copied from interface: WorkerPool

Asynchronously execute the given task using one of the threads of the worker pool. The task is expected to terminate gracefully, i.e. Runnable.run() should not throw an exception. Any uncaught exceptions should be logged by the worker pool implementation.

Specified by:

execute in interface WorkerPool

Parameters:

task - the task to execute

getActiveCount

public int getActiveCount()

Specified by:

getActiveCount in interface WorkerPool

getQueueSize

public int getQueueSize()

Specified by:

getQueueSize in interface WorkerPool

shutdown

public void shutdown(int timeout)
              throws InterruptedException

Description copied from interface: WorkerPool

Destroy the worker pool. The pool will immediately stop accepting new tasks. All previously submitted tasks will be executed. The method blocks until all tasks have completed execution, or the timeout occurs, or the current thread is interrupted, whichever happens first.

Specified by:

shutdown in interface WorkerPool

Parameters:

timeout - the timeout value in milliseconds

Throws:

InterruptedException - if the current thread was interrupted while waiting for pending tasks to finish execution
