Class MultiplexInt

java.lang.Object
org.jcsp.plugNplay.ints.MultiplexInt
All Implemented Interfaces:
CSProcess

public final class MultiplexInt extends 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 ();
 
   }
 
 }

      public MultiplexInt(AltingChannelInputInt[] in, ChannelOutputInt out)
      Construct a new MultiplexInt process with the input Channel in and the output Channels out. The ordering of the Channels in the in array make no difference to the functionality of this process -- the multiplexing services all channels fairly.
      Parameters:
      in - the input channels
      out - the output channel
