Class MutableGraphSupport

java.lang.Object
  org.tigris.gef.graph.MutableGraphSupport

All Implemented Interfaces:

BaseGraphModel, GraphModel, MutableGraphModel, java.io.Serializable

Direct Known Subclasses:

AdjacencyListGraphModel, DefaultGraphModel

public abstract class MutableGraphSupport

extends java.lang.Object

implements MutableGraphModel, java.io.Serializable

An abstract class that makes it easier to implement your own version of MutableGraphModel. This class basically includes the code for event notifications, so that you don't have to write that. It also provides a few utility methods.
