All Implemented Interfaces:

GraphModel, MutableGraphModel

Direct Known Subclasses:

SchematicGraphModel

public class BasicGraphModel
extends BasicModularGraphModel

A basic implementation of a mutable graph model that stores its graph structure as a collection of nodes and edges (as opposed to an adjacency matrix). This class is a good reference class for how to use the diva.graph.modular classes and will suffice as a data structure for simple, throw-away applications (a heavy-weight application like a schematic editor will probalby want to implement things differently.
