[Gabel-guys] Dispatcher

[Andy J. <and...@in...>]

  The dispatcher now lives!
  Here's the quick rundown...

. Starting a server is as easy as pie
  disp = new Dispatcher();
  disp.startServer();
. Making connection is as easy as pie
  disp = new Dispatcher();
  id = disp.connect(String host, int port);
  o Dispatcher makes the connection and return an identifier which should
    be used in future transactions
  o Dispatcher manages the Channel for you, will let you know when input
    comes { via accept(int, byte[]); }
  o Use write(int id, byte[]); to send data via the connection
. Any object interested in received dispatcher happenings should implemens
  the DispatcherSink interface, three methods
  o accept(int id, byte[] buff); // accept data
  o acceptConnection(int id); // accept connection
  o dropConnection(int id); // drop a connection
. Using this DispatcherSink it would be very easy to write a bridge class
  that implements the DispatcherSink and produces events which it then
  pushes into the event pool
. The other two classes SelectorWrapper.java and SelectionKeyAcceptor.java
  are really just internal classes, but may be useful if you want to wrap
  a selector for convience sake in the future
. Things to do...
  o Can't really stop the server, need to make the ServerSocketChannel a
    non-blocking Channel that is registered with the internal selector
    like anything else, able to stop
  o Non-connections are not detected
  o No clean way to disconnect channels yet
  o Add logger capabilities to error handling (currently println's)

THE SMURFS AND THE CUISINART (1986)
        The lovable little blue Smurfs encounter a lovable little kitchen
        appliance, which invites them to play.  The Smurfs learn a valuable
        (if sometimes fatal) lesson.

THE SMURFS AND THE CARBON-DIOXIDE INDUSTRIAL LASER (1987)
        The inevitable sequel.  The lovable and somewhat mangled surviving
        Smurfs team up with the Care Bears to encounter a cute, lovable piece
        of high-tech welding equipment, which teaches them the magic of
        becoming rather greasy smoke.  Heartwarming fun for the entire family.
