Defined in header <type_traits>
template< class T >
struct is_final;
(since C++14)

If T is a final class (that is, a class declared with the final specifier), provides the member constant value equal true. For any other type, value is false.

Contents

Inherited from std::integral_constant

Member constants

value
[static]
true if T is a final class type , false otherwise
(public static member constant)

Member functions

operator bool
converts the object to bool, returns value
(public member function)

Member types

Type Definition
value_type bool
type std::integral_constant<bool, value>

[edit] Notes

Final classes cannot be used as base classes.

A union can be marked final (and std::is_final will detect that), even though unions cannot be used as bases in any case.
