Interface Summary
Interface	Description
DestinationUserNameProvider	A `Principal` can also implement this contract when `getName()` isn't globally unique and therefore not suited for use with "user" destinations.
SimpSession	Represents a session of connected user.
SimpSubscription	Represents a subscription within a user session.
SimpSubscriptionMatcher	A strategy for matching subscriptions.
SimpUser	Represents a connected user.
SimpUserRegistry	A registry of currently connected users.
UserDestinationResolver	A strategy for resolving a "user" destination by translating it to one or more actual destinations one per active user session.

Class Summary
Class	Description

DefaultUserDestinationResolver.ParseResult	A temporary placeholder for a parsed source "user" destination.
MultiServerUserRegistry	`SimpUserRegistry` that looks up users in a "local" user registry as well as a set of "remote" user registries.
MultiServerUserRegistry.TransferSimpSession	SimpSession that can be (de)serialized and broadcast to other servers.
MultiServerUserRegistry.TransferSimpSubscription	SimpSubscription that can be (de)serialized and broadcast to other servers.
MultiServerUserRegistry.TransferSimpUser	SimpUser that can be (de)serialized and broadcast to other servers.
MultiServerUserRegistry.UserRegistrySnapshot	Holds a copy of a SimpUserRegistry for the purpose of broadcasting to and receiving broadcasts from other application servers.
UserDestinationMessageHandler	`MessageHandler` with support for "user" destinations.
UserDestinationMessageHandler.BroadcastHandler	A handler that broadcasts locally unresolved messages to the broker and also handles similar broadcasts received from the broker.
UserDestinationResult	Contains the result from parsing a "user" destination from a source message and translating it to target destinations (one per active user session).

Package org.springframework.messaging.simp.user Description

Also included is SimpUserRegistry for keeping track of connected user sessions.
