I am not sure:

   The catalog is quite flexible. It allows the caller of
   "catalog_object" to specify the uid under which the
   object should be cataloged.
   Only, if the uid is not provided (probably the normal
   use), it is computed from "getPhysicalPath".

   Of course, if it has been provided, the code above
   will break. Thus, "isObjectCataloged" is less general
   than "catalog_object".

   On the other hand, "getObject" will break too, when
   non-standard "uid"s are used. Thus, maybe, the
   "uid" feature should be scrapped.
