INTRO

Getty is a asynchronous network I/O library in golang. Getty works on tcp/udp/websocket network protocol and supplies a uniform interface.

In getty there are two goroutines in one connection(session), one reads tcp stream/udp packet/websocket package, the other handles logic process and writes response into network write buffer. If your logic process may take a long time, you should start a new logic process goroutine by yourself in codec.go:(Codec)OnMessage.

You can also handle heartbeat logic in codec.go:(Codec):OnCron. If you use tcp/udp, you should send hearbeat package by yourself, and then invoke session.go:(Session)UpdateActive to update its active time. Please check whether the tcp session has been timeout or not in codec.go:(Codec)OnCron by session.go:(Session)GetActive.

Whatever if you use websocket, you do not need to care about hearbeat request/response because Getty do this task in session.go:(Session)handleLoop by sending/received websocket ping/pong frames. You just need to check whether the websocket session has been timeout or not in codec.go:(Codec)OnCron by session.go:(Session)GetActive.
