public class DefaultGraphModel

extends MutableGraphSupport

implements Serializable

This interface provides a facade to a net-level representation. Similiar in concept to the Swing class TreeModel. This implementation of GraphModel uses the GEF classes NetList, NetNode, NetPort, and NetEdge. If you implement your own GraphModel, you can use your own application-specific classes.
