  • Method Details

    • run

      public void run()
      The monitoring thread, takes the next thread (servlet) that ran for longer than expected and kills it
      Specified by:
      run in interface java.lang.Runnable
      Overrides:
      run in class java.lang.Thread

    • register

      public static void register​(lazyj.BoundedThreadContainer btc)
      Register a thread that must be allowed to run but for a limited amount of time. This is used by the ExtendedServlet wrapper to keep under control the servlets, but you could use it for any other thread.
      Parameters:
      btc - the wrapper for the thread to be monitored

    • unregister

      public static void unregister​(lazyj.BoundedThreadContainer btc)
      Remove a previously added wrapper. Use this when the thread correctly finishes the work. You should explicitly call this when the work is done because otherwise you will probably kill something else that could be running later under that thread, and you don't want this, right? :)
      Parameters:
      btc -
