* Indicates that the annotated event handler method in {@link ChannelHandler} will not be invoked by
* {@link ChannelPipeline} and so MUST only be used when the {@link ChannelHandler}
* method does nothing except forward to the next {@link ChannelHandler} in the pipeline.
*
* Note that this annotation is not {@linkplain Inherited inherited}. If a user overrides a method annotated with
* {@link Skip}, it will not be skipped anymore. Similarly, the user can override a method not annotated with
* {@link Skip} and simply pass the event through to the next handler, which reverses the behavior of the
* supertype.
