vcl::comp::HasMark Concept Reference

HasMark concept is satisfied only if a Element/Mesh class provides the types and member functions specified in this concept. These types and member functions allow to access to a vcl::comp::Mark component of a given element/mesh. More...

Concept definition

template<typename T>
concept vcl::comp::HasMark =  requires (T&& obj) {
    { obj.mark() } -> std::same_as<int>;
 
    
    requires IsConst<T> || requires {
        { obj.resetMark() } -> std::same_as<void>;
        { obj.incrementMark() } -> std::same_as<void>;
        { obj.decrementMark() } -> std::same_as<void>;
    };
}

Detailed Description

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

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