All Implemented Interfaces:

ImageObserver, MenuContainer, Serializable, Accessible, yyDebug

public class yyAnim
extends Frame
implements yyDebug

delegates messages to a yyAnimPanel and optionally intercepts standard i/o. This is not Serializable.

If the panel is to simulate standard input it must be instantiated before standard input is accessed. Otherwise the reader might be waiting for a different stream.
