Example

The following example shows how to use Sign in a small program.
 import org.jcsp.lang.*;
 import org.jcsp.plugNplay.*;
 
 public class SignExample {
 
   public static void main (String[] argv) {
 
     final One2OneChannel[] a = Channel.one2oneArray (3);
     final One2OneChannel[] b = Channel.one2oneArray (3);
     final One2OneChannel c = Channel.one2one ();
 
     new Parallel (
       new CSProcess[] {
         new Numbers (a[0].out ()),
         new Fibonacci (a[1].out ()),
         new Squares (a[2].out ()),
         new Sign ("Numbers ", a[0].in (), b[0].out ()),
         new Sign ("            Fibonacci ", a[1].in (), b[1].out ()),
         new Sign ("                          Squares ", a[2].in (), b[2].out ()),
         new Plex (Channel.getInputArray (b), c.out ()),
         new Printer (c.in (), "", "\n")
       }
     ).run ();
 
   }
 
 }
