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 ();
}
}

Times
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 Channelin2
- the second input Channelout
- the output Channel
