+                    corresponding framework-cache.
+                    We use given "sFactory" value to decide which query must be used to fill "pContainer" with new values.
+                    Given "pContainer" hold us alive as uno reference and we use it to synchronize it with framework caches.
+                    We will die, if he die! see dtor for further information.
