getReplacement	back to summary
public SurfaceData getReplacement() Implements abstract sun.java2d.SurfaceData.getReplacement. Doc from sun.java2d.SurfaceData.getReplacement. Certain changes in the configuration of a surface require the invalidation of existing associated SurfaceData objects and the creation of brand new ones. These changes include size, ColorModel, or SurfaceType. Existing Graphics objects which are directed at such surfaces, however, must continue to render to them even after the change occurs underneath the covers. The getReplacement() method is called from SunGraphics2D.revalidateAll() when the associated SurfaceData is found to be invalid so that a Graphics object can continue to render to the surface in its new configuration. Such changes only tend to happen to window based surfaces since most image based surfaces never change size or pixel format. Even VolatileImage objects never change size and they only change their pixel format when manually validated against a new GraphicsConfiguration, at which point old Graphics objects are no longer expected to render to them after the validation step. Thus, only window based surfaces really need to deal with this form of replacement.
