      • runCallback

        public final void runCallback()
        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.

      • run

        public final void run()
        Run the callback object first, then invoke runHandle().

      • runHandle

        public abstract void runHandle()
        Invoke an action to be performed periodically for a statistics Handle.

        Synchronization has to be handled by the method itself.
