Class GraphItem

java.lang.Object
  g2d.glyph.Identifiable
      g2d.glyph.Attributable
          g2d.glyph.Glyphish
              g2d.graph.GraphItem

All Implemented Interfaces:

KeyListener, MouseListener, MouseMotionListener, EventListener

Direct Known Subclasses:

IOPEdge, IOPNode

public abstract class GraphItem
extends Glyphish

Methods common to nodes and edges in a graph.

Both 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.
