org.jacorb.notification.queue
Class BoundedDeadlineEventQueue

java.lang.Object
  org.jacorb.notification.queue.AbstractBoundedEventQueue
      org.jacorb.notification.queue.AbstractBoundedEventHeap
          org.jacorb.notification.queue.BoundedDeadlineEventQueue

All Implemented Interfaces:

MessageQueue

public class BoundedDeadlineEventQueue
extends AbstractBoundedEventHeap

Note that most of the methods are not thread-safe. this causes no problem as the methods are not intended to be directly called by clients. instead the superclass implements the interface EventQueue and invokes the methods thereby synchronizing access.
