    @short          ctor
    @descr          These initialize an instance of a SfxFilterListener class. Created object listen automaticly
                    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 syschronize it with framework caches.
                    We will die, if he die! see dtor for further informations.

    @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
    @return         -

    @onerror        We show some assertions in non product version.
                    Otherwise we do nothing!
    @threadsafe     yes
