public class UseCaseDiagramGraphModel

extends MutableGraphSupport

implements MutableGraphModel, VetoableChangeListener

This class defines a bridge between the UML meta-model representation of the design and the GraphModel interface used by GEF. This class handles only UML Use Case Digrams.

Field Detail

_nodes

protected Vector _nodes

_edges

protected Vector _edges

_model

protected Namespace _model

The "home" UML model of this diagram, not all ModelElements in this graph are in the home model, but if they are added and don't already have a model, they are placed in the "home model". Also, elements from other models will have their FigNodes add a line to say what their model is.
