public interface ProtocolDecoder
Decodes binary or protocol-specific data into higher-level message objects.

method with read data, and then the decoder implementation puts decoded
messages into ProtocolDecoderOutput by calling
ProtocolDecoderOutput.write(Object).
Please refer to
TextLineDecoder
example.
