Save out a PrintWriter file upon exit (Read 613 times)

Save out a PrintWriter file upon exit
Feb 11th, 2010, 4:34pm  
I've got a PrintWriter object that I want to save (flush) and close out whenever the sketch is quit.  Currently, I'm trying to catch that this way:

public void stop() {
 output.flush();  //Write the remaining data
 output.close();  //Finish the file
 super.stop();
}

I was hoping this would run the needed .flush() and .close() no matter how sketch was quit.

But it's not working — my printwriter files turn up empty.  Any thoughts?

Never mind — I got it!

Instead of calling .flush() in stop(), I call it after every time that I output more data to the file, as in:

   output.println("one line of data goes here");
   output.flush();  //Write the data to file

Then I call .close() in stop().  Not sure if that's a proper approach, but it's working.
