Interface ExtendedGraphics2D

public interface ExtendedGraphics2D

An interface which allows to detect Groups in the Node structure. This can be used by specific Graphics2D to allow to keep the original Node structure. For example, a SVG Graphics2D converter might create a "g" Node for each Node in the tree to regroup its children.

Usage

The Graphics2DConverter does not use this interface by default when converting a Node tree. However, it is possible to use a ConverterListener to process specificaly the Groups. An example of usage could be:

 public void startNode(Graphics2D g2D, Node node) {
   if (node instanceof Parent) {
     if (g2D instanceof ExtendedGraphics2D) {
       ExtendedGraphics2D group2D = (ExtendedGraphics2D)g2D;
       group2D.startGroup(node.getId(), node);
     }
   }
 }

 public void endNode(Graphics2D g2D, Node node) {
   if (node instanceof Parent) {
     if (g2D instanceof ExtendedGraphics2D) {
       ExtendedGraphics2D group2D = (ExtendedGraphics2D)g2D;
       group2D.endGroup(node);
     }
   }
 }
