{@link StateContext} objects are used to store the current {@link State} andany application specific attributes for a specific client of a {@link StateMachine}. Since {@link StateMachine}s are singletons and shared by all clients using the {@link StateMachine} this is where client specificdata needs to be stored. @author The Apache MINA Project (dev@mina.apache.org) @version $Rev: 586695 $, $Date: 2007-10-20 12:01:17 +0200 (Sat, 20 Oct 2007) $
