Detailed Description

template<class t_VARIANT, size_t t_INDEX>
struct bslstl::Variant_CVQualAlt< t_VARIANT, t_INDEX >

This component-private metafunction calculates the alternative type at index (template parameter) t_INDEX in (template parameter) t_VARIANT, where the cv- and ref-qualifiers of t_VARIANT are added to the alternative type. This metafunction is used to calculate the return type of bsl::visit.
