Class ClientSession

java.lang.Object
io.netty.channel.ChannelHandlerAdapter
io.netty.channel.ChannelInboundHandlerAdapter
crow.game.examples.pingpong.client.ClientSession
All Implemented Interfaces:
io.netty.channel.ChannelHandler, io.netty.channel.ChannelInboundHandler
public class ClientSession extends io.netty.channel.ChannelInboundHandlerAdapter
This contains the state and netty behavior of the ping pong client.

We use scheduleAtFixedRate to trigger pings from the client to server as a keepalive. The HA rathena code performs application-level ping/pong so this is an example for eventual usage in that module.

We send 5 pings in an interval and then cancel the recurring task them which should trigger an idle event on the server, and the server will kill the connection. This helps test a few assumptions and designs that will go into the main server(s).
