Description

NandInt is a process whose output strean is the bitwise nand of the integers on its input streams.

Channel Protocols

All channels in this package carry integers.

Input Channels
in0, in1	int
Output Channels
out	int	All channels in this package carry integers.

Example

The following example shows how the use of this process in a small program. The program also uses some of the other building block processes. It generates a sequence of numbers, rounds each odd number down to the nearest even number, negates them and prints them to the screen.

 import org.jcsp.lang.*;
 import org.jcsp.plugNplay.ints.*;
 
 public class NandIntExample {
 
   public static void main (String[] argv) {
 
     final One2OneChannelInt a = Channel.one2oneInt ();
     final One2OneChannelInt b = Channel.one2oneInt ();
     final One2OneChannelInt c = Channel.one2oneInt ();
     final One2OneChannelInt d = Channel.one2oneInt ();
 
     new Parallel (
       new CSProcess[] {
         new NumbersInt (a.out ()),
         new GenerateInt (b.out (), Integer.MAX_VALUE - 1),
         new NandInt (a.in (), b.in (), c.out ()),
         new SuccessorInt (c.in (), d.out ()),
         new PrinterInt (d.in (), "--> ", "\n")
       }
     ).run ();
 
   }
 
 }

Constructor Detail

NandInt

public NandInt(ChannelInputInt in0,
               ChannelInputInt in1,
               ChannelOutputInt out)

Construct a new NandInt 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.

Parameters:

in0 - the first input Channel

in1 - the second input Channel

out - the output Channel
