Hi Trustin I read the source code(1.1.6) ProtocolEncoderImpl<http://mina.apache.org/report/1.1/xref/org/apache/mina/filter/codec/demux/DemuxingProtocolCodecFactory.html>.
1)Set<Class<?>> messageTypes = encoder.getMessageTypes(); is used to get the message of concrete encoder class. 2)in encode method: Class<?> type = message.getClass(); MessageEncoder<http://mina.apache.org/report/1.1/xref/org/apache/mina/filter/codec/demux/MessageEncoder.html>encoder = findEncoder(type); --How mina find out what encoder should be used, right? Therefore, if I have to register my concrete encoder class to TYPES and also implement public Set<Class<?>> getMessageTypes() { return TYPES; } However in your previous answer, you said getMessageTypes in NO use? Which means in Mina2.0, it is NO use?
