| /** Components can implement <code>XUnloadingPreference</code> in order to indicate |
| how they should be treated when their hosting library is to be unloaded. |
| |
| When someone calls <code>rtl_unloadUnusedModules</code> 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. <br> |
| 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 <code>releaseOnNotification</code>. If the function |
| returns false then the listener should keep the reference, otherwise |
| it may release it. |
