Package jay.yydebug

Class yyAnim

  • All Implemented Interfaces:
    java.awt.image.ImageObserver, java.awt.MenuContainer, java.io.Serializable, javax.accessibility.Accessible, yyDebug
    public class yyAnim
extends java.awt.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.
