ilog.cpl.graph
Class IlpDefaultNodeRenderer

java.lang.Object
  ilog.cpl.graph.IlpDefaultNodeRenderer

All Implemented Interfaces:

IlpNodeRenderer

Direct Known Subclasses:

IlpDefaultNetworkRenderer

public class IlpDefaultNodeRenderer
extends Object
implements IlpNodeRenderer

This class creates and updates the IlpGraphic objects that represent an IlpRepresentationObject object.

This renderer works as follows. First, it fetches the graphicRenderer property in the CSS customization. If one is found, it is used. This renderer provides no additional functionality. If no such renderer is found, or if its createGraphic function returns null, this renderer uses the view's default renderer.

Since:

JTGO 4.0
