Class BroadcastSchedulerListener

java.lang.Object
  extended by org.quartz.listeners.BroadcastSchedulerListener
All Implemented Interfaces:
SchedulerListener

public class BroadcastSchedulerListener
extends Object
implements SchedulerListener

Holds a List of references to SchedulerListener instances and broadcasts all events to them (in order).

This may be more convenient than registering all of the listeners directly with the Scheduler, and provides the flexibility of easily changing which listeners get notified.
