| <p><span class="bold"><strong>Remark</strong></span>: Automatically detects if T has a nested allocator_type that is convertible from Allocator. Meets the BinaryTypeTrait requirements ([meta.rqmts] 20.4.1). A program may specialize this type to define uses_allocator<X>::value as true for a T of user-defined type if T does not have a nested allocator_type but is nonetheless constructible using the specified Allocator.</p> |
| <p><span class="bold"><strong>Result</strong></span>: uses_allocator<T, Allocator>::value== true if Convertible<Allocator,T::allocator_type>, false otherwise. </p> |
