std::tuple_element<array>

template <size_t I, class Tpl> class tuple_element;   // unspecializedtemplate <size_t I, class T, size_t N>  struct tuple_element <I, array<T,N>>;               // array specialization

Tuple element type for array

Accesses the static type of the elements in an array object as if it was a tuple.

This class specialization simply provides a member

type, which aliases T, as if defined as:

template <size_t I, class Tpl> class tuple_element;
template <size_t I, class T, size_t N> struct tuple_element <I, array<T,N>>
{
  typedef T type;
};

See tuple_element for more information.

Template parameters

I: Order number of the element within the array (zero-based).
All elements in an array object have the same static type, and thus this is not relevant for this specialization. But a program is ill-formed if I>=N.
size_t is an unsigned integral type.
Tpl: Tuple-like type: array<T,N>.
T: Type of the elements contained.
Aliased as member type.
N: Size of the array, in terms of number of elements.

Member types
