interface XUnloadingPreference
Description
Components can implement XUnloadingPreference in order to indicate how they should be treated when their hosting library is to be unloaded. When someone calls rtl_unloadUnusedModules then the unloading listeners are notified by calling previously registered callback functions. A listener is an entity that employs, registers, and unregisters the callback functions on its behalf. Upon notification (the callback function is being called) a listener may release references to UNO components. Thus, the loaded libraries can be unloaded, if no one else keeps any objects from the library alive.
Before a listener releases references, it should ask for this interface. If the interface is not implemented, then the listener may release the object; otherwise, it calls releaseOnNotification. If the function returns false then the listener should keep the reference, otherwise it may release it.
