Shell Class

Used to retrieve the standard output stream. Returns a List that can be parsed while the executable is still running or after is has been run. The difference lies in when the run method is invoked. The following is an example of how to process the output stream while the app is running. The getOutput() is called BEFORE the run() method is invoked.

    File exe = new File("C:\\Program Files\\PostgreSQL\\8.4\\bin\\shp2pgsql.exe");
    String[] options = new String[]{"-W", "UTF-8", "-s", "4326", "C:\country.shp", "t_country"};

    javaxt.io.Shell cmd = new javaxt.io.Shell(exe, options);
    java.util.List<String> output = cmd.getOutput();
    cmd.run();

    String line;
    while (true){
        synchronized (output) {
            while (output.isEmpty()) {
              try {
                  output.wait();
              }
              catch (InterruptedException e) {
              }
            }
            line = output.remove(0);
        }

        if (line!=null){
            System.out.println(line);
        }
        else{
            break;
        }
    }    

If you want to get the entire output all at once, just call the getOutput() AFTER the run() method. Example:

    javaxt.io.Shell cmd = new javaxt.io.Shell(exe, options);
    cmd.run();
    java.util.List<String> output = cmd.getOutput();
    for (int i=0; i<output.size(); i++){
        System.out.println(output.get(i));
    }    

Used to retrieve the error output stream. Returns a List that can be parsed while the executable is still running or after is has been run.

Used to execute the process specified in the constructor and populate the output streams.

Used to stop the current process. Note that this method does not stop or kill process grandchildren. This is a limitation of Java, not this class per se. See Sun bug 4770092 for more details.

Used to return the total time (milliseconds) it took to execute the process.
