Netty 4 ChannelInboundMessageHandlerAdapter(Netty 4 ChannelInboundMessageHandlerAdapter)
Which methods of class ChannelInboundMessageHandlerAdapter will actually get called when this class has been instantiated and connected to a pipeline? obviously messageReceived is (as was the case in Netty 3). What about the other methods listed on its documentation?
Must an implementation override any of its other methods other than messageReceived in order to process messages?
You only need to override messageReceived to process messages. You "can" override others if you want some "special" handling.
