It is not necessary for the end user to + * explicitly delete these objects. However, when the Java2D/OpenGL + * pipeline is active and frame buffer objects are being used for + * rendering, it is necessary for all OpenGL contexts created by JOGL + * to share server-side objects with the Java2D OpenGL context. This + * means that these objects "leak" into the namespace used by Java2D. + * In order to prevent memory leaks and to present the same + * programming model to the end user, it is necessary to track the + * creation and destruction of all of these server-side OpenGL objects + * and to explicitly release them when all of the JOGL-created + * contexts which can see them have been released. <P> + * + * The {@link #ref ref} and {@link #unref unref} methods should be + * used during the creation and destruction of OpenGL contexts by JOGL + * in order to update the liveness of the objects being tracked. The + * various other methods should be called by the OpenGL binding in the + * various named methods. + */ + +public class GLObjectTracker { + private static final boolean DEBUG = Debug.debug("GLObjectTracker");
