Interface MutableGraphModel

All Superinterfaces:

BaseGraphModel, GraphModel, java.io.Serializable

All Known Implementing Classes:

AdjacencyListGraphModel, DefaultGraphModel, MutableGraphSupport

public interface MutableGraphModel
extends GraphModel

This interface provides a facade to a net-level representation. Similiar in concept to the Swing class TreeModel.

This interface goes beyond GraphModel in that it allows modifications to the graph, instead of just access.
