[MINA] how could i get a custom MessageDecoder?

[Donald]

hi Trustin:
I find the MessageDecoder in DemuxingProtocolCodecFactory can not
custom a flexible strategy.Now it be used like this:

    super.register( AddMessageDecoder.class );

Buf if i want use different MessageDecoder according to different
connection,like this :
    MyMessageDecoder(ConnectionStrategyManager manager){
                 //....
    }
and when come a message, i use the manager to decide how to decode the
input bytes, how can i do?

Could i regist a Message Decoder like this:

   ConnectionStrategyManager manager = //...;
   super.register(new MyMessageDecoder(manager));

so we can use a flexible singleton messageDecoder in coming message,can we?

thanks!

Donald
