io.netty.channel.SimpleChannelInboundHandler<BigInteger>

io.netty.example.factorial.FactorialClientHandler

All Implemented Interfaces:

ChannelHandler, ChannelInboundHandler

public class FactorialClientHandler
extends SimpleChannelInboundHandler<BigInteger>

Handler for a client-side channel. This handler maintains stateful information which is specific to a certain channel using member variables. Therefore, an instance of this handler can cover only one channel. You have to create a new handler instance whenever you create a new channel and insert this handler to avoid a race condition.
