    Description

    This is a process with an infinite loop that waits for a Object of type Number to be sent down each of its input channels. The loop body then calculates the bitwise XOR on the values of the two Numbers and writes the result as a new Integer to its output channel.

    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 to use the Xor process in a small program. The program also uses some of the other building block processes. It generates a sequence of numbers, XORs them with Integer.MAX_VALUE to give a decending sequence of numbers (from Integer.MAX_VALUE) and prints this on the screen.

         One2OneChannel b = Channel.one2one ();
         One2OneChannel c = Channel.one2one ();
     
         new Parallel (
           new CSProcess[] {
             new Numbers (a.out ()),
             new Generate (b.out (), Integer.MAX_VALUE),
             new Xor (a.in (), b.in (), c.out ()),
             new Printer (c.in (), "--> ", "\n")
           }
