Package com.aspectran.core.util.thread

Class ScheduledExecutorScheduler

java.lang.Object

com.aspectran.core.util.thread.ScheduledExecutorScheduler

All Implemented Interfaces:

Scheduler

public class ScheduledExecutorScheduler
extends java.lang.Object
implements Scheduler

Implementation of Scheduler based on JDK's ScheduledThreadPoolExecutor.

While use of ScheduledThreadPoolExecutor creates futures that will not be used, it has the advantage of allowing to set a property to remove cancelled tasks from its queue even if the task did not fire, which provides a huge benefit in the performance of garbage collection in young generation.
