std::move_iterator::base(3) C++ Standard Libary std::move_iterator::base(3) NAME std::move_iterator::base - std::move_iterator::base Synopsis iterator_type base() const; (since C++11) (un- til C++17) constexpr iterator_type base() const; (1) (since C++17) (un- til C++20) constexpr const iterator_type& base() const& noexcept; (since C++20) constexpr iterator_type base() &&; (2) (since C++20) Returns the underlying base iterator. 1) Copy constructs the return value from the underlying iterator. (until C++20) 1) Returns a reference to the underlying iterator. (since C++20) 2) Move constructs the return value from the underlying iterator. Parameters (none) Return value 1) A copy of the underlying iterator. (until C++20) 1) A reference to the underlying iterator. (since C++20) 2) An iterator move constructed from the underlying iterator. Exceptions May throw implementation-defined exceptions. Example // Run this code #include <algorithm> #include <iostream> #include <iterator> #include <vector> int main() { std::vector<int> v{ 0, 1, 2, 3, 4 }; std::move_iterator<std::vector<int>::reverse_iterator> m1{ v.rbegin() }, m2{ v.rend() }; std::copy(m1.base(), m2.base(), std::ostream_itera- tor<int>(std::cout, " ")); std::cout << '\n'; } Output: 4 3 2 1 0 Defect reports The following behavior-changing defect reports were applied retroac- tively to previously published C++ standards.
