Class GraphLayoutCacheEvent

java.lang.Object

java.util.EventObject

org.jgraph.event.GraphLayoutCacheEvent

All Implemented Interfaces:

java.io.Serializable

public class GraphLayoutCacheEvent
extends java.util.EventObject

Encapsulates information describing changes to a graph layout cache, and is used to notify graph layout cache listeners of the change. Note that graph layout cache events do not repeat information in graph model events if there is no view specific information. The idea of this event is to provide information on what has changed in the graph layout cache only.
