[Multicast] using APR transport

[Lorenz Breu]

Hi guys

I am trying to implement some form of multicast capability in the MINA 
framework. I see that you have started to implement the classes for APR 
support. My first attempt therefor is to create a multicast 
AprDatagramAcceptor. However the documentation of the APR stuff seems a 
bit on the minimal side. I now have some questions one of you APR-guys 
may be able to answer:

The receive method needs to return the SocketAddress of the sender of 
the received datagram. How can I access that data using the APR API?? Do 
I have to parse the received data at the byte level, or does APR somehow 
prepare that information in a struct somewhere?


On a different note, why did you never implement a simple multicast 
acceptor using the MultiCastSocket of java.io? Is it just a performance 
thing? Thread management is done in the AbstractPollingIoAcceptor and 
should also work unchanged with java.net, or am I missing something?

Regards,
Lorenz
