/**
 * Keeps a JID and the information about that JID together.

 * <li>{@link nu.fw.jeti.backend.roster.PrimaryJIDStatus}</li>
 * <li>{@link nu.fw.jeti.backend.roster.NormalJIDStatus}</li>
 * <li>{@link nu.fw.jeti.backend.roster.ResourceJIDStatus}</li>
 * </ul>
 * These classes are part of the roster and are used to store and sort
 * information about the nickname and resources. This abstract class makes the most
 * used methods of those classes available, so the implementing classes are rarely needed.
 * The JIDStatussen available in the roster can be obtained by {@link Backend#getJIDStatus(JID)}
 * If you need your own jidstatus you can use {@link UnknownJIDStatus}
