Short explanation - Player session has the addHandler method. Please check out Session interface from which it is inheriting.
Long explanation: - Once the player is connected to room then you need to listen for events and/or send events to the remote client. You can use playerSession.addHandler(eventHandler) to add event handler. To see the pre-defined set of events take a look at Events class. Now you will notice that there are many events, but mostly you will be listening for SESSION_MESSAGE and writing back NETWORK_MESSAGE.
You have 2 options here, 1) Implement a eventhandler which handles session message event to receive game data. 2) You can override the DefaultSessionEventHandler , and override the onDataIn method to receive events, benefit of using this implementation is that it takes care of other events with default logic. An example of its use is the Zombie Session Handler
Related to public List getEventHandlers(int eventType) method - The event type is part of the EventHandler Interface,check out the getEventType method or the example games directory for further assistance. Let me know if this clears your doubt.

Thanks for long explanation. The thing is that I want to change playerSession handler from handler1 to handler2. I think the current API does not provide straightforward solution.

The reason why there is no "resetHandlers" is that if you remove all handlers then you need to set up the low level network communication protocol by yourself and that is not trivial. Apart from this, the addHandler method is provided to add handlers, so you can do your "addHandler(GameHandler)" on top of existing protocol. Protocol is configured using spring meaning it can be replaced, or plugged in with your own if required. Take a look at this bean file. If there is any other easier approach you think of, let me know

b.t.w removing a specific handler can be done like sessionInstance.getEventDispatcher().removeHandlersForEvent(Events.CONNECT);// You can put in any event of your choice here. Take a look at EventDispatcher methods. The session interface is only exposing a few of the methods on the event dispatcher for sake of ease. Maybe I should add removeHandlersForEvent to session interface also.

sessionInstance.getEventDispatcher().removeHandlersForEvent(Events.CONNECT);
This is seems to be what I have asked for. Thanks
