Description
The Or class is a process which has an infinite loop that waits
a Object of type Number to be sent down each of the in1 and in2 Channels.
The process then calculates the bitwise OR on the intValue() of the
two Numbers then write the result as a new Integer down the out 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 Or process in a small program.
The program also uses some of the other building block processes. The
program generates a sequence of numbers and rounds each even number up to
the nearest odd number and prints this on the screen.
import org.jcsp.lang.*;
import org.jcsp.plugNplay.*;
public class OrExample {
public static void main (String[] argv) {
final One2OneChannel a = Channel.one2one ();
final One2OneChannel b = Channel.one2one ();
final One2OneChannel c = Channel.one2one ();
final One2OneChannel d = Channel.one2one ();
new Parallel (
new CSProcess[] {
new Numbers (a.out ()),
new Generate (b.out (), 1),
new Or (a.in (), b.in (), c.out ()),
new Successor (c.in (), d.out ()),
new Printer (d.in (), "--> ", "\n")
}
).run ();
}
}

Or
public Or(ChannelInput in1,
ChannelInput in2,
ChannelOutput out)
- Construct a new Or 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()
- The main body of this process.
