Detailed Description

template<class t_TYPE, template< class > class t_TRAIT>
struct bslmf::DetectNestedTrait< t_TYPE, t_TRAIT >

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.
