Class MultiplexInt

  • All Implemented Interfaces:
    CSProcess

    public final class MultiplexInt
    extends java.lang.Object
    implements CSProcess
    Fair multiplexes its input integer stream array into one output stream (carrying source channel and data pairs).

    Process Diagram

    Description

    MultiplexInt is a process to convert multiple streams of ints to a single stream in such a way that it can be de-multiplexed later. The protocol on the outgoing multiplexed stream consists of an int, that represents the channel identity of the multiplexed data, followed by the multiplexed data.

    The ordering of the channels in the in array makes no difference to the functionality of this process -- the multiplexing services all channels fairly.

    Channel Protocols

    Input Channels
    in[] int All channels in this package carry integers.
    Output Channels
    out int, int An out message is an index followed by the multiplexed data.

    Example

    The following example shows how to use MultiplexInt in a small program.
     import org.jcsp.lang.*;
     import org.jcsp.plugNplay.ints.*;
     
     public class MultiplexIntExample {
     
       public static void main (String[] argv) {
     
         final One2OneChannelInt[] a = Channel.one2oneIntArray (3);
         final One2OneChannelInt b = Channel.one2oneInt ();
     
         new Parallel (
           new CSProcess[] {
             new NumbersInt (a[0].out ()),
             new FibonacciInt (a[1].out ()),
             new SquaresInt (a[2].out ()),
             new MultiplexInt (Channel.getInputArray (a), b.out ()),
             new CSProcess () {
               public void run () {
                 String[] key = {"Numbers ",
                                 "            Fibonacci ",
                                 "                          Squares "};
                 while (true) {
                   System.out.print (key[b.in ().read ()]);   // print channel source
                   System.out.println (b.in ().read ());      // print multiplexed data
                 }
               }
             }
           }
         ).run ();
     
       }
     
     }
