Trustin Lee commented on DIRMINA-160:

This is a message from J-F.  I put this here to track this issue more easily:


Hi Niklas,

I suggested this some time ago. As Mina is asynchronous, this leads indeed to
state-based protocol handler.

It would be a great idea to develop code that could be reused.

The State pattern can help:

Unfortunately, I don't know any open-source implementation of it.

practices for building complex protocols on top of MINA.

which demultiplexes events to an appropriate IoHandler implementation according to a certain
session attribute value.
> I guess we could provide some means for defining the states and transitions too.
