/** 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.
