Method Summary

abstract void	draw(DrawableCombiner dc, Primitive primitive, Object obj, ViewportJ2D vp) Draws the primitive.
void	prepareAndExecuteDraw(DrawableCombiner dc, Primitive primitive, Object obj, ViewportJ2D vp) Prepares the object for rendering to a Java2D viewport
static boolean	setupDCMatrix(DrawableCombiner dc, Object obj, boolean enablePos, boolean enableSize, boolean enableRot, ViewportJ2D vp) Sets the basic matrix for the combiner, call can be skipped if alternative draw method is required.
protected boolean	setupMatrix(DrawableCombiner dc, Primitive primitive, Object obj, Graphics2D g, IViewport vp) Sets up the transformation matrix before drawing.

prepareAndExecuteDraw

public final void prepareAndExecuteDraw(DrawableCombiner dc,
                                        Primitive primitive,
                                        Object obj,
                                        ViewportJ2D vp)

Prepares the object for rendering to a Java2D viewport

Specified by:

prepareAndExecuteDraw in interface IJ2DRenderer

Parameters:

dc - the DrawableCombiner drawing the object

primitive - the primitive being drawn

obj - the object being drawn

vp - the viewport

setupDCMatrix

public static final boolean setupDCMatrix(DrawableCombiner dc,
                                          Object obj,
                                          boolean enablePos,
                                          boolean enableSize,
                                          boolean enableRot,
                                          ViewportJ2D vp)

Sets the basic matrix for the combiner, call can be skipped if alternative draw method is required.

Parameters:

obj - object being drawn

g - the viewport context

enablePos - enables position setup

enableSize - enables size setup

enableRot - enables rotation setup

setupMatrix

protected boolean setupMatrix(DrawableCombiner dc,
                              Primitive primitive,
                              Object obj,
                              Graphics2D g,
                              IViewport vp)

Sets up the transformation matrix before drawing.

Parameters:

obj - object being drawn

g - graphics context

Returns:

true, if the setup was successful

draw

public abstract void draw(DrawableCombiner dc,
                          Primitive primitive,
                          Object obj,
