public class ExtendedResultHandler extends SystemRun.ResultHandler {

  public String result_or_error;

  public void onProcessComplete(int exitValue) {
      super.onProcessComplete(exitValue);
      result_or_error = getResultString();
  }

  public void onProcessFailed(ExecuteException e) {
      super.onProcessFailed(e);

execCommand

public static SystemRun.ResultHandler execCommand(java.lang.String cmd,
                                  long timeout)
                                           throws java.io.IOException

execute command string and return SystemRun.ResultHandler when execution end or timed out

Parameters:

cmd - Command string

timeout - Process execution time out

Returns:

ResultHandler

Throws:

java.io.IOException

execCommand

public static void execCommand(org.apache.commons.exec.CommandLine cmd,
               long timeout,
               SystemRun.ResultHandler handler)
                        throws java.io.IOException

execute asynchronously.
if timeout is not set, sub-process may not end. So if use DefaultExecuteResultHandler.waitFor(), may be waiting for infinitely.

Parameters:

cmd - CommandLine

timeout - Process execution time out

handler - ResultHandler

Throws:

java.io.IOException
