Class PeriodicRunnable

java.lang.Object

com.sun.identity.common.GeneralTaskRunnable

com.sun.identity.common.PeriodicRunnable

All Implemented Interfaces:

TaskRunnable, Runnable

Direct Known Subclasses:

PeriodicGroupRunnable

public class PeriodicRunnable
extends GeneralTaskRunnable

Periodic task (task will be run periodically) which has handler integrated (implements ScheduleableAction) can be scheduled to Timer or TimerPool by using PeriodicRunnable. All the elements in the same PeriodicRunnable must have the same timeout period and run period. Elements will be grouped by using the time they enter PeriodicRunnable. Elements which entered PeriodicRunnable excess the timeout time will be checked 1 by 1 and ScheduleableAction (doAction()) will be invoked.
