Method Detail

start

public void start()

starts the JdkDispatcherThread and ExecutorServices

Specified by:

start in interface JobExecutor

Specified by:

start in class AbstractJobExecutor

stop

public void stop()

Description copied from interface: JobExecutor

stops with join set to false.

Specified by:

stop in interface JobExecutor

Specified by:

stop in class AbstractJobExecutor

stop

public void stop(boolean join)

Description copied from interface: JobExecutor

signals to all threads managed by this jobImpl executor to stop. Stopping the dispatcher thread is blocking till the dispatcher is no more alive. If join is set to true, this method will block until all jobImpl executor threads are joined and actually dead. If join is false, the jobImpl executor threads are only told to stop, without waiting till they are actually stopped. It may be that jobImpl executor threads are in the middle of executing a jobImpl and they may finish after this method returned.

Specified by:

stop in interface JobExecutor

Specified by:

stop in class AbstractJobExecutor

waitTillQueueEmpty

protected void waitTillQueueEmpty()

getDispatcherThread

public JdkDispatcherThread getDispatcherThread()

Specified by:

getDispatcherThread in class AbstractJobExecutor

getAcquireJobSize

protected int getAcquireJobSize()

Specified by:

getAcquireJobSize in class AbstractJobExecutor

getExecutorService

public java.util.concurrent.ExecutorService getExecutorService()

Returns:

the executorService
