Class Xor

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.
import org.jcsp.lang.*;
import org.jcsp.plugNplay.*;
public class XorExample {
public static void main (String[] argv) {
One2OneChannel a = Channel.one2one ();
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")
}
).run ();
}
}

Xor
public Xor(ChannelInput in1,
ChannelInput in2,
ChannelOutput out)
- Construct a new Xor 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 Channelin2
- The second input Channelout
- The output Channel
run
public void run()
