* A {@link ChannelHandler} that is notified when it is added to or removed
* from a {@link ChannelPipeline}.
*
* <h3>Invalid access to the {@link ChannelHandlerContext}</h3>
*
* Calling {@link ChannelHandlerContext#sendUpstream(ChannelEvent)} or
* {@link ChannelHandlerContext#sendDownstream(ChannelEvent)} in
* {@link #beforeAdd(ChannelHandlerContext)} or {@link #afterRemove(ChannelHandlerContext)}
* will lead to an unexpected behavior. It is because the context object has
* not been fully added to the pipeline or the context object is not a part of
* the pipeline anymore respectively.
