Description

Times is a process whose output stream is the product of the Integers on its input streams.

Channel Protocols

Input Channels
in1,in2 java.lang.Number Both Channels can accept data from any subclass of Number. It is possible to send Floats down one channel and Integers down the other. However 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 the use of this process in a small program. The program also uses some of the other building block processes. It generates two sequences of numbers, multiplies them together and prints them to the screen.
 import org.jcsp.lang.*;
 import org.jcsp.plugNplay.*;
 
 public class TimesExample {
 
   public static void main (String[] argv) {
 
     final One2OneChannel a = Channel.one2one ();
     final One2OneChannel b = Channel.one2one ();
     final One2OneChannel c = Channel.one2one ();
 
     new Parallel (
       new CSProcess[] {
         new Numbers (a.out ()),
         new Numbers (b.out ()),
         new Times (a.in (), b.in (), c.out ()),
         new Printer (c.in (), "--> ", "\n")
       }
     ).run ();
 
   }
 
 }

      public Times(ChannelInput in1, ChannelInput in2, ChannelOutput out)
      Construct a new Times process with the input Channels in1 and in2 and the output Channel out. The ordering of the Channels in1 and in2 make no difference to the functionality of this process.
      Parameters:
      in1 - the first input Channel
      in2 - the second input Channel
      out - the output Channel
