Examples of de.fu_berlin.inf.dpp.User

de.fu_berlin.inf.dpp.User
A user is a representation of a person sitting in front of an eclipse instance for the use in one Saros session. A user object always has the following immutable characteristics: He/she belongs to a single ISarosSession, has a final color, and fixed JID. There is one user who is the host, all others are clients. There is one local user representing the person in front of the current eclipse instance, all others are buddies. The public and mutable properties are the {@link User.Permission}, time since going off-line, connection state, away information and whether this user is still joining or already part of the session. @entityObject A user is a entity object, i.e. it can change over time.


            // By now we should have returned or have a RQ-JID
            assert presenceJID.isResourceQualifiedJID();


            // Get the user (if any)
            User user = sarosSession.getUser(presenceJID);
            if (user == null)
                return; // PresenceJID does not identify a user in the project


            assert user.getJID().strictlyEquals(presenceJID);


            if (presence.isAvailable()) {
                if (user.getConnectionState() != UserConnectionState.ONLINE) {
                    user.setConnectionState(User.UserConnectionState.ONLINE);
