CSP for Java
(JCSP) 1.1-rc4

Class XorInt

  extended by org.jcsp.plugNplay.ints.XorInt
All Implemented Interfaces:

public final class XorInt
extends Object
implements CSProcess

Bitwise xors two integer streams to one stream.

Process Diagram

    in0  ________
   -->--|        | out
    in1 | XorInt |-->--


XorInt is a process whose output strean is the bitwise xor of the integers on its input streams.

Channel Protocols

Input Channels
in1,in2 int All channels in this package carry integers.
Output Channels
out int All channels in this package carry integers.


The following example shows how to use this process in a small program. The program also uses some of the other building block processes. It generates a sequence of numbers, XORs them with Integer.MAX_VALUE to give a decending sequence of numbers (from Integer.MAX_VALUE) and prints this on the screen.
 import org.jcsp.lang.*;
 import org.jcsp.plugNplay.ints.*;
 public class XorIntExample {
   public static void main (String[] argv) {
     One2OneChannelInt a = Channel.one2oneInt ();
     One2OneChannelInt b = Channel.one2oneInt ();
     One2OneChannelInt c = Channel.one2oneInt ();
     new Parallel (
       new CSProcess[] {
         new NumbersInt (a.out ()),
         new GenerateInt (b.out (), Integer.MAX_VALUE),
         new XorInt (a.in (), b.in (), c.out ()),
         new PrinterInt (c.in (), "--> ", "\n")
     ).run ();

Constructor Detail


public XorInt(ChannelInputInt in0,
              ChannelInputInt in1,
              ChannelOutputInt out)
Construct a new XorInt process with the input Channels in0 and in1 and the output Channel out. The ordering of the Channels in0 and in1 make no difference to the functionality of this process.

in0 - The first input Channel
in1 - The second input Channel
out - The output Channel
Method Detail


public void run()
The main body of this process.
