Note that this class subclasses from the {@link Image} class, whichincludes methods that take an {@link ImageObserver} parameter forasynchronous notifications as information is received from a potential {@link ImageProducer}. Since this VolatileImage is not loaded from an asynchronous source, the various methods that take an ImageObserver parameter will behave as if the data has already been obtained from the ImageProducer. Specifically, this means that the return values from such methods will never indicate that the information is not yet available and the ImageObserver used in such methods will never need to be recorded for an asynchronous callback notification. @since 1.4
