      extended by org.eclipse.draw2d.graph.Subgraph

public class Subgraph
extends Node

A Node which may contain other nodes. A Subgraph is a compound or container node. It may have incoming and outgoing edges just like a node. Subgraphs are used in CompoundDirectedGraphs. A proper layout of a compound graph ensures that all of a subgraph's children are placed inside its rectangular region. Nodes which do not belong to the subgraph must be placed outside that region.

A Subgraph may contain another Subgraph.

A Subgraph has additional geometric properties which describe the containing box. They are:
