CSProcess
Bitwise ands two Integer streams to one stream.
Process Diagram
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 AND on the values of the two Numbers and writes the result as a new Integer to its output channel.
Channel Protocols
Input Channels | ||
---|---|---|
in0, in1 | 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 And 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 odd number down to the nearest even number and prints this on the screen.import org.jcsp.lang.*; import org.jcsp.plugNplay.*; public class AndExample { 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 Generate (b.out (), Integer.MAX_VALUE - 1), new And (a.in (), b.in (), c.out ()), new Printer (c.in (), "--> ", "\n") } ).run (); } }
