org.jacorb.notification.queue

Class BoundedPriorityEventQueue

java.lang.Object

org.jacorb.notification.queue.AbstractBoundedEventQueue

org.jacorb.notification.queue.AbstractBoundedEventHeap

org.jacorb.notification.queue.BoundedPriorityEventQueue

All Implemented Interfaces:

MessageQueue

public class BoundedPriorityEventQueue
extends AbstractBoundedEventHeap

Note that the methods do not need to be 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.
