Class UserNameManager

java.lang.Object
  org.jivesoftware.openfire.user.UserNameManager

public class UserNameManager
extends Object

Main responsibility of this class is to return the correct name of XMPP entities. For local entities (i.e. users) the User name is used. For remote entities the following logic is used:

1. Check if a UserNameProvider is registered for the entity's domain. If a provider was found then use it to get the entity's name
2. If no provider was found then retrieve the vCard of the entity and return the name as defined in the vCard. This is not implemented yet.
3. If no vCard was found then return the string representation of the entity's JID.
