NAME¶

std::ranges::adjacent_transform_view::adjacent_transform_view - std::ranges::adjacent_transform_view::adjacent_transform_view

Synopsis¶

adjacent_transform_view() = default; (1) (since C++23)
constexpr explicit adjacent_transform_view( V base, F fun ); (2) (since C++23)

Constructs an adjacent_transform_view.

1) Default constructor. Default-initializes the underlying data members fun_ and
inner_.
2) Move constructs the underlying data members: fun_ with std::move(fun) and inner_
with std::move(base).

Parameters¶

base - the underlying view
fun - the N-ary transformation function

Example¶

// Run this code

#include <algorithm>
#include <iostream>
#include <iterator>
#include <ranges>

int main()
{
constexpr static auto v = {1, 2, 3, 4, 5};
constexpr auto mul = [](auto... x) { return (... * x); };
constexpr auto view = std::views::adjacent_transform<3>(v, mul);
std::ranges::copy(view, std::ostream_iterator<int>(std::cout, " "));
std::cout << '\n';
}
