              ecologylab.services.authentication.nio.AuthClientManager

All Implemented Interfaces:

AuthMessages, AuthServerRegistryObjects, NetworkingConstants, ServerConstants

public class AuthClientManager
extends ClientManager
implements ServerConstants, AuthServerRegistryObjects, AuthMessages

Stores information about the connection context for the client, including authentication status. Only executes requests from an authenticated client. Should be extended for more specific implementations. Handles accumulating incoming messages and translating them into RequestMessage objects.
