public class IoHandlerAdapter
extends java.lang.Object

IoHandler

, MINA will close the connection automatically.

sessionCreated
public void sessionCreated(IoSession session)
throws Exception
Invoked from an I/O processor thread when a new connection has been created.
Because this method is supposed to be called from the same thread that
handles I/O of multiple sessions, please implement this method to perform
tasks that consumes minimal amount of time such as socket parameter
and user-defined session attribute initialization.

sessionIdle
public void sessionIdle(IoSession session,
IdleStatus status)
throws Exception

This method is not invoked if the transport type is UDP; it's a known bug,
and will be fixed in 2.0.
