Constant Field Values

ignoreClipHeuristic

protected boolean ignoreClipHeuristic

If true, no attempt will be made to discard geometry based on it being out of bounds. This trades potentially drawing many out of bounds shapes with having to recalculate bounding boxes every animation iteration.

Constructor Detail

SVGDiagram

public SVGDiagram(URI xmlBase,
                  SVGUniverse universe)

Creates a new instance of SVGDiagram

Parameters:

xmlBase -

universe -

Method Detail

render

public void render(Graphics2D g)
            throws SVGException

Draws this diagram to the passed graphics context

Parameters:

g -

Throws:

SVGException

pick

public List<List<SVGElement>> pick(Point2D point,
                                   List<List<SVGElement>> retVec)
                            throws SVGException

Searches thorough the scene graph for all RenderableElements that have shapes that contain the passed point. For every shape which contains the pick point, a List containing the path to the node is added to the return list. That is, the result of SVGElement.getPath() is added for each entry.

Parameters:

point -

retVec -

Returns:

the passed in list

Throws:

SVGException

pick

                            throws SVGException

Throws:
