Class MapChangeAdapter

java.lang.Object
  wyvern.lib.event.MapChangeAdapter

All Implemented Interfaces:

java.util.EventListener, MapChangeListener

public class MapChangeAdapter

extends java.lang.Object

implements MapChangeListener

An abstract adapter class for receiving map change events. The methods in this class are empty. This class exists as a convenience for creating listener objects.

Extend this class to create a MapChangeEvent listener, and override the methods for the events of interest. (If you implement the MapChangeListener interface, you have to define all of the methods in it. This abstract class defines null methods for them all, so you only have to define methods for events you care about.)

Create a listener object using the extended class and then register it with a map using the map's addMapChangeListener method. When the map is loaded, suspended, resumed, or unloaded, the relevant method in the listener object is invoked, and the MapChangeEvent is passed to it.
