    • runCallback

      public final void runCallback()
      Deprecated.
      Run the callback object. This will happen at the start of each invocation of a Handle's run() method. The callback is presumed to be exception safe. If no callback is set, this is a no-op. The callback will need to handle any necessary synchronization itself.

    • runHandle

      public abstract void runHandle()
