Class StreamGobbler  

java.lang.Object
  java.lang.Thread
      com.jguild.jrpm.test.StreamGobbler

All Implemented Interfaces:

java.lang.Runnable

---

public class StreamGobbler

extends java.lang.Thread

This class reads an input stream in an extra thread. This is used for running external programms out of java so that stdout and stderr are not blocking the process from work. If the stream is closed by Runtime the gobbler will also die. Usage:

 Process proc = Runtime.getRuntime().exec(command);

 // any error message?
 StreamGobbler errorGobbler = new StreamGobbler(rpmProc.getErrorStream(), System.err);

 // any output?
 StreamGobbler outputGobbler = new StreamGobbler(rpmProc.getInputStream(), System.out);

 // kick them off
 errorGobbler.start();
 outputGobbler.start();
