Interface  Description 

EdgeController 
Specifies the interface for objects that manage creation
of and interaction with graph edges.

EdgeRenderer 
A factory which creates a visual representation (EdgeFigure)
given an edge input.

GraphController 
A class that represents the main component of a typical graph
editor.

GraphListener 
A listener for changes in a graph's structure or contents,
which are communicated through GraphEvent objects.

GraphModel 
A graph model is an abstraction of a graph implementation and a
registration point for GraphListeners.

GraphViewListener 
A listener for changes in a graph's structure or contents,
which are communicated through GraphViewEvent objects.

MutableGraphModel 
A mutable graph model is a readwrite subclass of the readonly
graph model, allowing users to actually create new nodes and
edges, and to modify the topology of the graph.

NodeController 
Specifies the interface for objects that manage creation
of and interaction with graph nodes.

NodeRenderer 
A factory which creates a visual representation (Figure)
given a node input.

Class  Description 

AbstractGraphController 
An abstract implementation of the GraphController interface.

AbstractGraphModel 
An abstract implementation of the GraphModel interface that provides
the basic event notification system

BasicEdgeController 
A basic implementation of EdgeController, which works with
graphs that have edges connecting simple nodes.

BasicNodeController 
A basic node controller implementation, intended for use
as a controller for graphs containing only one node type.

EdgeCreator 
An interactor that interactively drags edges from one node
to another.

EdgeInteractor 
An interactor for edges.

GraphEvent 
A graph event that is emitted when anything interesting happens
inside a graph by way of a GraphModel.

GraphPane 
The display part of the JGraph userlevel widget.

GraphUtilities 
A set of utilities for traversing/manipulating/etc. graphs.

GraphViewEvent 
A graph view event that is emitted when anything interesting happens
inside a graph view.

JGraph 
A graph widget analogous to java.swing.JTree.

NodeDragInteractor 
An interactor that drags nodes.

NodeInteractor 
An interactor for nodes.

SimpleGraphController 
A simple graph controller, which works well if all nodes have the same
interaction, and all edges have the same interaction.

Exception  Description 

GraphException 
A graph package topological error.

A generic and highlyextensible graph visualization library whose basic interface is a widget analogous to java.swing.JTree. The diva.graph collection of packages provides three central pieces of functionality:
For a taste of how this library works in its most basic form, the following piece of code instantiates a basic graph, containing two nodes connected by an edge ( A > B ).
// Construct the widgets
Frame f = new Frame();
JGraph g = new JGraph();
f.add("Center", g);// Construct the graph
BasicNode a = new BasicNode("a");
BasicNode b = new BasicNode("b");
BasicEdge e = new BasicEdge("e");
jg.getModel().addNode(a);
jg.getModel().addNode(b);
jg.getModel().connect(e, a, b);// Display it all
f.setVisible(true);
