  • Method Details

    • run

      boolean run() throws IOException
      Run the logic. This method allows throwing an interrupted exception on wakeup, but the implementation does not have to. It is preferred to finish the work elegantly and return a boolean to indicate whether all the jobs have been done or more invocation is needed.
      Returns:
      whether the runnable has successfully finished running.
      Throws:
      IOException - when the performed I/O operation fails.

    • wakeUp

      void wakeUp()
      Wake up the running thread.
