Vaadin Collaboration Engine 3.2.0.alpha3

Refactored PresenceManager API

The PresenceManager, introduced in 3.2.0.alpha2, has been improved based on feedback.

• setAutoPresence has been renamed to markAsPresent

PresenceManager presence = new PresenceManager(users, ownUserInfo, topicId);
presence.markAsPresent(true);

• getUsers method has been removed from the public API. The method always returned 0 before the connection was established, which lead to confusion. Developers should now register a NewUserHandler if they want keep track of the users as they are added or removed from a topic.
  Example: Keeping a list of users in a topic.

// Create your own list to keep track of the users in the topic
List<UserInfo> userList = ...;
// ...
presenceManager.setNewUserHandler(userInfo -> {
    // Add the new user to the local list when she joins the topic
    userList.add(userInfo);
    return () -> {
        // Remove the user from the local list when she leaves the topic
        userList.remove(userInfo);
    };
});
