This metafunction provides an appropriate iterator adaptor for the specified (template parameter) type `ITERATOR` in order to implement members of the `vector` partial template specialization for vectors of pointers to the (template parameter) type `TARGET`. The metafunction will return the original `ITERATOR` type unless it truly is an iterator, using `is_integral` as a proxy for testing that a type is NOT an iterator. This is needed to disambiguate only the cases of users passing `0` as a null‐pointer value to functions requesting a number of identical copies of an element.
