A TransformationTrait is a class template that provides a transformation of its template type parameter.

[edit] Requirements

  • Takes one template type parameter (additional template parameters are optional and allowed).
  • The transformed type is a publicly accessible nested type named type.

[edit] Standard library

All type transformation traits satisfy TransformationTrait.

The following standard library class templates also satisfy TransformationTrait.

obtains the type of the specified element
(class template specialization) [edit]
obtains the type of the elements of pair
(class template specialization) [edit]
obtains the type of the elements of array
(class template specialization) [edit]
obtains the type of the alternative specified by its index, at compile time
(class template) (alias template)[edit]
