NAME¶

std::ranges::adjacent_view::iterator::operator* - std::ranges::adjacent_view::iterator::operator*

Synopsis¶

constexpr auto operator*() const; (since C++23)

Returns the elements into V the underlying array of iterators points to.

Let current_ be an underlying array of iterators.

Equivalent to:

return __tuple_transform([](auto& i) -> decltype(auto) { return *i; }, current_);

Parameters¶

(none)

Return value¶

The current element, which is a std::tuple of references to underlying elements.

Notes¶

operator-> is not provided.

Example¶

// Run this code

#include <ranges>
#include <tuple>

int main()
{
constexpr static auto v = {0, 1, 2, 3, 4, 5};
// └──┬──┘
// └─────────────────┐
constexpr auto view {v | std::views::adjacent<3>}; // │
constexpr auto iter {view.begin() + 2}; // │
// ┌────────────────────┬────────────────┘
// │ ┌──┴──┐
static_assert(*iter == std::tuple{2, 3, 4});
}
