Class DispatchEventHandler

  org.rioproject.event.EventHandler
      org.rioproject.event.DispatchEventHandler

public class DispatchEventHandler
extends EventHandler

The DispatchEventHandler provides an implementation of an EventHandler which supports the notification of events to all registered event listeners with a valid lease.

Event registrations are leased and explicitly checked prior to each notification being sent to the remote event listener

The sequence number for events is incremented after each subsequent fire invocation.
