@short ctor
@descr These initialize an instance of a SfxFilterListener class. Created object listen automatically
on right FilterFactory-Service for all changes and synchronize right SfxFilterContainer with
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.
@seealso dtor
@seealso class framework::FilterCache
@seealso service ::document::FilterFactory
@param "sFactory" , short name of module which contains filter container
@param "pContainer", pointer to filter container which will be informed
@onerror We show some assertions in non product version.
Otherwise we do nothing!
