org.jboss.netty.channel.ChannelPipeline.replace()
Replaces the specified {@link ChannelHandler} with a new handler inthis pipeline. @throws NoSuchElementException if the specified old handler does not exist in this pipeline @throws IllegalArgumentException if a handler with the specified new name already exists in this pipeline, except for the handler to be replaced @throws NullPointerException if the specified old handler, new name, or new handler is {@code null}
