Class PariProcess

Object
  PariProcess

public class PariProcess

extends Object

Maintains a Pari process and provides send(java.lang.String) and receive() methods for communicating with it. It's hard-coded for Pari under Windows, in that it uses \r\n as the signal that a computation is finished.

Important: call destroy() when you're done to close Pari and release I/O resources.

Method Detail

send

public void send(String s)
          throws IOException

Sends its argument to Pari, followed by a newline. Sample usage: send("2+2"). You can end the line with semicolon to mean you don't want output, as long as there are no trailing comments or whitespace after the semicolon.

Throws:

IOException

receive

public String receive()

Returns the result of the previous send(java.lang.String). Don't use it if the previous send(java.lang.String) ended in a semicolon, so that you don't expect any output from it.

main

public static void main(String[] args)

Runs a simple test.
