I read the source code of IoUtil and found this class is simply to do the loop job for sending messages to all the sessions . I wonder if this kind of class is really neccessary in mina core since in my opinion it makes mina core too big. Furthermore, if the IoUtil could do something like helping encode the Object message(IoBuffer of course uses duplicate is OKAY) once for all the sessions, which will be more meaningful. Am I right? Thanks.
