  • Method Summary

    Modifier and Type Method Description
    boolean isRunning()
    This method can be consulted to find out whether the monitor is running.
    static void main​(String[] args)
    Main method starting the foldermonitor that looks for changes to a monitored folder.
    void run()
    When an object implementing interface Runnable is used to create a thread, starting the thread causes the object's run method to be called in that separately executing thread.
    void signalStop()
    This method can be used to signal the monitor to halt its monitoring.

  • Method Details

    • run

      public void run()
      When an object implementing interface Runnable is used to create a thread, starting the thread causes the object's run method to be called in that separately executing thread.

      The general contract of the method run is that it may take any action whatsoever.

      Specified by:
      run in interface Runnable
      See Also:
      Thread.run()
    • signalStop

      public void signalStop()
      This method can be used to signal the monitor to halt its monitoring.
    • isRunning

      public boolean isRunning()
      This method can be consulted to find out whether the monitor is running.
      Returns:
      boolean that indicates whether the monitor is running.
    • main

      public static void main​(String[] args)
      Main method starting the foldermonitor that looks for changes to a monitored folder.
      Parameters:
      args - start-up arguments
