Detailed Description

template<class t_TYPE, template< class > class t_TRAIT, class = void>
struct bslmf::DetectNestedTrait_Imp< t_TYPE, t_TRAIT, class >

Metafunction to detect whether the specified t_TRAIT parameter is associated with the specified t_TYPE parameter using the nested type trait mechanism. The nested type is an alias for bsl::false_type unless t_TYPE is a class type that the user has associated with the specified trait using the BSLMF_NESTED_TRAIT_DECLARATION macro. Class types detect such association in the specialization below.
