std::ranges::adjacent_view
(C++26)
adjacent_view::iterator::operator*
Member functions
Non-member functions
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_);
Contents
[edit] Parameters
(none)
[edit] Return value
The current element, which is a std::tuple of references to underlying elements.
[edit] Notes
operator-> is not provided.
[edit] 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}); }
