Method Summary

IlpGraphic	createGraphic(IlpGraphicView view, IlpRepresentationObject object, IlpAttribute attribute, IlpGraphicRendererContext rendererContext) Creates a new IlpGraphic from an IlpRepresentationObject and optional attribute.
void	updateGraphic(IlpGraphic g, IlpGraphicRendererContext rendererContext) Updates an existing IlpGraphic.

Method Detail

createGraphic

IlpGraphic createGraphic(IlpGraphicView view,
                         IlpRepresentationObject object,
                         IlpAttribute attribute,
                         IlpGraphicRendererContext rendererContext)

Creates a new IlpGraphic from an IlpRepresentationObject and optional attribute.

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.

Parameters:

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

object - The representation object.

attribute - The attribute in the representation object.

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

updateGraphic

void updateGraphic(IlpGraphic g,
                   IlpGraphicRendererContext rendererContext)

Updates an existing IlpGraphic.

Parameters:

g - The graphic to be updated.

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