std::experimental::ranges::DerivedFrom: std::experimental::ranges::DerivedFrom


std::experimental::ranges::DerivedFrom - std::experimental::ranges::DerivedFrom


Defined in header <experimental/ranges/concepts>
template < class T, class U >
concept bool DerivedFrom = (ranges TS)
std::is_base_of<U, T>::value &&
std::is_convertible<std::remove_cv_t<T>*, std::remove_cv_t<U>*>::value;

The concept DerivedFrom<T, U> is satisfied if and only if U is a class type that is either T or a public and unambiguous base of T.
Despite the use of std::is_base_of and std::is_convertible in its description above, DerivedFrom is not required to use it in its implementation. Thus, there need not be any subsumption relationship between DerivedFrom<T, U> and std::is_base_of<U,T>::value or std::is_convertible<std::remove_cv_t<T>*, std::remove_cv_t<U>*>::value.
