Package jay.yydebug

Class yyInputStream

java.lang.Object

java.io.InputStream

jay.yydebug.yyInputStream

All Implemented Interfaces:

KeyListener, Closeable, AutoCloseable, EventListener

public class yyInputStream
extends InputStream
implements KeyListener

used to reroute standard input from a TextArea. Feeds all read methods from listening to typed keys. Should not deadlock because one should generally not read from within the event thread.

While this implementation uses Java generics, code for a non-generic version has simply been commented out.
