:mrdocs:

This class detects if the specified class `TYPE` has STL‐like iterators. If the class `TYPE` provides STL‐like iterators then `HasStlIterators<TYPE>::value == true`, and `HasStlIterators<TYPE>::value == false` otherwise.

| This `struct` template metafunction detects whether the specified `t_TRAIT` parameter is associated with the specified `t_TYPE` parameter using the nested type trait mechanism. This trait derives from `bsl::true_type` if and only if `t_TYPE` is a class type that associated with the specified trait using the `BSLMF_NESTED_TRAIT_DECLARATION` macro, and from `bsl::false_type` otherwise. Users should not specialize this trait directly for their types, but should always use the macro to make a nested trait association.
