All Implemented Interfaces:

ActionListener, WindowListener, ImageObserver, MenuContainer, Serializable, EventListener, Accessible, ReplicatedHashMap.Notification<Object,Object>

public class ReplicatedHashMapDemo
extends Frame
implements WindowListener, ActionListener, ReplicatedHashMap.Notification<Object,Object>

Uses the ReplicatedHashMap building block, which subclasses java.util.HashMap and overrides the methods that modify the hashmap (e.g. put()). Those methods are multicast to the group, whereas read-only methods such as get() use the local copy. A ReplicatedHashMap is created given the name of a group; all hashmaps with the same name find each other and form a group.
