public interface MessageHandler

Developers implement MessageHandlers in order to receive incoming messages during a web socket conversation. Each web socket session uses no more than one thread at a time to call its MessageHandlers. This means that, provided each message handler instance is used to handle messages for one web socket session, at most one thread at a time can be calling any of its methods. Developers who wish to handle messages from multiple clients within the same message handlers may do so by adding the same instance as a handler on each of the Session objects for the clients. In that case, they will need to code with the possibility of their MessageHandler being called concurrently by multiple threads, each one arising from a different client session.
