Class ThreadedFileWriter

java.lang.Object
  java.lang.Thread
      org.jpop.io.ThreadedFileWriter

All Implemented Interfaces:

java.lang.Runnable

public abstract class ThreadedFileWriter

extends java.lang.Thread

This class takes a BufferedReader and a File object, then opens the file for writing and reads whatever is interfacethe buffered reader until this is empty whilst writing to the file the contents. At the end it closes both the file and the reader and stops. To use this class, you must define methods for all the events:

  ThreadedFileWriter tfw = new ThreadedFileWriter(filename, reader){
      public void exceptionGenerated(Exception e){
          // stuff to do when an exception is fired
      }
      public void fileChanged(){
          //stuff to do when file changes
      }
      public void fileClosed(){
          // stuff to do when file is closed
      }
      public void fileOpened(){
          // stuff to do when file is opened
      }
  }.start();
