Class ActionCoordinator

java.lang.Object
  ucar.unidata.ui.event.ActionCoordinator

All Implemented Interfaces:

EventListener, ActionValueListener

public class ActionCoordinator
extends Object
implements ActionValueListener

An ActionCoordinator helps manage the set of objects that send and receive an ActionValueEvent. It is assumed that each event generator is also interested in recieving the event if its from someone else; these objects are of type ActionSourceListener. For each kind of event, an ActionCoordinator object is created. When it gets an event, it sends it to all others who have registered except not to the event source.
