Interface UserDestinationResolver

All Known Implementing Classes:

DefaultUserDestinationResolver

public interface UserDestinationResolver

A strategy for resolving a "user" destination by translating it to one or more actual destinations one per active user session. When sending a message to a user destination, the destination must contain the user name so it may be extracted and used to look up the user sessions. When subscribing to a user destination, the destination does not have to contain the user's own name. We simply use the current session.

See implementation classes and the documentation for example destinations.
