Class PrefixInt

java.lang.Object
  org.jcsp.plugNplay.ints.PrefixInt

All Implemented Interfaces:

CSProcess

public final class PrefixInt
extends Object
implements CSProcess

Prefixes a user-supplied integer to the int stream flowing through.

Process Diagram

Description

This is a process which first outputs a given integer and then copies its input stream of integers to its output stream.

One output is gererated before any input but, thereafter, one output is produced for each input.

Channel Protocols

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

Implementation Note

The implementation uses an IdentityInt process for the copy loop:

   public void run () {
     out.write (n);                        // prefix the given integer to the stream
     new IdentityInt (in, out).run ();     // copy the stream
   }
