Class AdjacencyListGraphModel

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

All Implemented Interfaces:

java.io.Serializable, BaseGraphModel, GraphModel, MutableGraphModel

public abstract class AdjacencyListGraphModel
extends MutableGraphSupport
implements java.io.Serializable

This class is an example of an alternative way to implement MutableGraphModel. Needs-more-work: this code has not been used or tested.
