Can you justify the need for this abstraction?

[Sergey Ulanov, 2011/04/18 19:40:28]

That's mainly to make it easier to unittest code that uses TCPServerSocket. I
could just make corresponding methods virtual in TCPSocketServer, but I think
having an interface is cleaner. I'll remove it if you disagree.

I see. I had thought you were planning on using this polymorphically in
production code. Coding to interfaces is good and makes testing easier, so I'm
fine with this as is.
