Interface IlpNodeRenderer

All Known Subinterfaces:

IlpNetworkRenderer

All Known Implementing Classes:

IlpDefaultNetworkRenderer, IlpDefaultNodeRenderer

public interface IlpNodeRenderer

This interface defines the basic renderer for a graphic object in the view.

It allows the creation and updating of an IlpGraphic object, which will represent either an IlpRepresentationObject or a specific attribute of this object.

Since:

JTGO 4.0

Method Summary

IlpGraphic	createGraphic(IlpGraphView view, IlpRepresentationObject object, IlpGraphicRendererContext rendererContext, IlpGraphic previousGraphic) Creates a new IlpGraphic from an IlpRepresentationObject.
void	updateGraphic(IlpGraphic graphic, IlpGraphicRendererContext rendererContext) Updates an existing IlpGraphic.

Method Detail

createGraphic

IlpGraphic createGraphic(IlpGraphView view,
                         IlpRepresentationObject object,
                         IlpGraphicRendererContext rendererContext,
                         IlpGraphic previousGraphic)

Creates a new IlpGraphic from an IlpRepresentationObject.

The graphic object will be used in the specified view. An implementation of this method should always create a new IlpGraphic instance, as instances may be cached externally. This method should return the completely constructed graphic object. It may internally call updateGraphic. If the previousGraphic argument is non-null, this method may - as an optimization - choose to reuse the previousGraphic instead of creating a new one.

Parameters:

view - Graphic view in which the object will be displayed.

object - The representation object.

rendererContext - The context which carries information to be used in the rendering process, such as selection information.

previousGraphic - The previous graphic object for this object, for possible optimization, or null.

updateGraphic

void updateGraphic(IlpGraphic graphic,
                   IlpGraphicRendererContext rendererContext)

Updates an existing IlpGraphic.

Parameters:

graphic - The graphic to be updated.

rendererContext - The context which carries information to be used in the rendering process, such as selection information.
