37 * The Cancelable interface defines a common method of adding general <i>disable-and-exit</i>
38 * semantics to some object. By cancel()ing a Cancelable object, a request is
39 * made to disable that object.
41 * <b>Disabling</b>
43 * A cancel()ed object may not necessarily abort it work immediately. Often, it much more
44 * elegant for a cancel()ed object to complete handling whatever responsibilities have
45 * been assigned to it, but it will <i>not</i> take on any new responsibility.
47 * <b>Exiting</b>
49 * A cancel()ed should complete its responsibilities as soon as possible.
50 * Canceling is not only a request to stop taking on new responsibility, and to
51 * complete its current responsibility. Its also a request to complete dealing with its
52 * current responsibilities, quickly when possible.

67 * @post The Cancelable object will have permanently transitioned to a
68 * disabled state; it will now refuse to accept new responsibility.
