Package org.jcsp.plugNplay

Class Mult

java.lang.Object

org.jcsp.plugNplay.Mult

All Implemented Interfaces:

CSProcess

public final class Mult
extends Object
implements CSProcess

Scales an Integer stream.

Process Diagram

Description

Mult multiplies each Integer that flows through it by the multiplier with which it is configured.

Channel Protocols

Input Channels
in	java.lang.Number	The Channel can accept data from any subclass of Number. All values will be converted to ints.
Output Channels
out	java.lang.Integer	The output will always be of type Integer.

Example

The following example shows how to use the Mult process in a small program. The program also uses some of the other plugNplay processes. The program generates a sequence of Integers, multiplies them by 42 and prints this on the screen.

 import org.jcsp.lang.*;
 import org.jcsp.plugNplay.*;
 
 public class MultExample {
 
   public static void main (String[] argv) {
 
     final One2OneChannel a = Channel.one2one ();
     final One2OneChannel b = Channel.one2one ();
 
     new Parallel (
       new CSProcess[] {
         new Numbers (a.out ()),
         new Mult (42, a.in (), b.out ()),
         new Printer (b.in (), "--> ", "\n")
       }
     ).run ();
 
   }
 
 }
