g2d.graph

Class GraphItem

java.lang.Object

g2d.jlambda.Identifiable

g2d.jlambda.Attributable

g2d.glyph.Glyphish

g2d.graph.GraphItem

All Implemented Interfaces:

java.awt.event.KeyListener, java.awt.event.MouseListener, java.awt.event.MouseMotionListener, java.util.EventListener

Direct Known Subclasses:

IOPEdge, IOPNode, IOPSubgraph

public abstract class GraphItem
extends Glyphish

Methods common to nodes and edges in a graph.

Subgraphs, nodes and edges are lists of glyphs in their manifestation. However, instead of exposing this glyph list as the superclass of either, this abstract class encapsulates the glyph list used for manifestation and exposes in its interface only the Glyphish class.
