Interface GraphModel

All Known Subinterfaces:

MutableGraphModel

public abstract interface GraphModel

extends Serializable

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

The idea is not to have a widget (like JGraph) storing all the information that it should display, and the programmer having to keep the widget's data in synch with the application's data. Instead, the programmer defines a Model class that gives the widget access to the application data. That way there is only one copy of the data and nothing can get out of synch. If you don't have your own application data objects, there is a Default implementation of the Model that will store it for you.

Instead of asking application programmers to subclass their data objects from some predefined base class (like NetNode), this interface allows the use of any application object as a node, port, or edge. This makes it much easier to add a visualization to an existing application.
