Method Summary

int	getPoolSize()
void	initialize() Called by the QuartzScheduler before the ThreadPool is used, in order to give the it a chance to initialize.
boolean	runInThread(Runnable runnable) Execute the given Runnable in the next available Thread.
void	shutdown(boolean waitForJobsToComplete) Called by the QuartzScheduler to inform the ThreadPool that it should free up all of it's resources because the scheduler is shutting down.

Method Detail

runInThread

public boolean runInThread(Runnable runnable)

Execute the given Runnable in the next available Thread.

The implementation of this interface should not throw exceptions unless there is a serious problem (i.e. a serious misconfiguration). If there are no available threads, rather it should either queue the Runnable, or block until a thread is available, depending on the desired strategy.

initialize

public void initialize()
                throws SchedulerConfigException

Called by the QuartzScheduler before the ThreadPool is used, in order to give the it a chance to initialize.

Throws:

SchedulerConfigException

shutdown

public void shutdown(boolean waitForJobsToComplete)

Called by the QuartzScheduler to inform the ThreadPool that it should free up all of it's resources because the scheduler is shutting down.

getPoolSize

public int getPoolSize()
