Class yyJInputStream
java.lang.Object
java.io.InputStream
jay.yydebug.yyJInputStream
- All Implemented Interfaces:
KeyListener
,Closeable
,AutoCloseable
,EventListener
used to reroute standard input from a
JTextArea
.
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 avoids Java generics, code for a generic version has simply been commented out.

keyPressed
this one ensures that you can only type at the end and implements control-C as copy and control-V as paste key if AWTPermission(accessClipboard) is granted. This is executed within the event thread.BUG: paste should be based on the platform paste key; however, Safari does not send that one to an applet.
