Concept definition

template<typename T>
concept vcl::comp::HasPrincipalCurvature =  requires (T&& obj) {
    typename RemoveRef<T>::PrincipalCurvatureType;
    { obj.principalCurvature() } -> PrincipalCurvatureConcept;
}

Detailed Description

HasPrincipalCurvature concept is satisfied only if a Element class provides the types and member functions specified in this concept. These types and member functions allow to access to a vcl::comp::PrincipalCurvature component of a given element.

Note that this concept does not discriminate between the Horizontal PrincipalCurvature component and the vertical OptionalPrincipalCurvature component, therefore it does not guarantee that a template Element type that satisfies this concept provides PrincipalCurvature component at runtime (it is guaranteed only that the proper member functions are available at compile time).
