/**
 * The XMPPRoomHybridStorage class is designed to be easily extensible.
 * The class has several protected methods that act as hooks,
 * allowing you to override various methods to customize the functionality how you see fit.
 * 
 * This header file lists the protected methods,
 * and you may need to import it in your subclass if you ever need to invoke these methods directly.
 * 
 * E.g. [super insertOccupant...]
