java.lang.Objectorg.apache.mina.filter.codec.demux.DemuxingProtocolCodecFactory
public class DemuxingProtocolCodecFactory
A composite ProtocolCodecFactory
that consists of multiple
MessageEncoder
s and MessageDecoder
s.
ProtocolEncoder
and ProtocolDecoder
this factory
returns demultiplex incoming messages and buffers to
appropriate MessageEncoder
s and MessageDecoder
s.
MessageEncoder
and MessageDecoder
Make your MessageEncoder
and MessageDecoder
to put all
resources that need to be released as a session attribute. disposeCodecResources(IoSession)
method will be invoked when a session is closed. Override disposeCodecResources(IoSession)
to release the resources you've put as an attribute.
We didn't provide any dispose method for MessageEncoder
and MessageDecoder
because they can give you a big performance penalty in case you have a lot of
message types to handle.

disposeCodecResources(IoSession session)
Implement this method to release all resources acquired to perform encoding and decoding messages for the specified session. |
ProtocolDecoder |
getDecoder()
Returns a new (or reusable) instance of ProtocolDecoder which
decodes binary or protocol-specific data into message objects. |
ProtocolEncoder |
getEncoder()
Returns a new (or reusable) instance of ProtocolEncoder which
encodes message objects into binary or protocol-specific data. |
