org.jboss.netty.example.factorial.FactorialServerHandler
- All Implemented Interfaces:
ChannelHandler
,ChannelUpstreamHandler
Handler for a server-side channel. This handler maintains stateful

to create a new handler instance whenever you create a new channel and insert
this handler to avoid a race condition.
