std::ranges...t_view::base(3) C++ Standard Libarystd::ranges...t_view::base(3) NAME std::ranges::split_view::base - std::ranges::split_view::base Synopsis constexpr V base() const& requires std::copy_constructible<V>; (1) (since C++20) constexpr V base() &&; (2) (since C++20) Returns a copy of the underlying view base_. 1) Copy constructs the result from the underlying view. 2) Move constructs the result from the underlying view. Parameters (none) Return value 1) A copy of the underlying view. 2) A view move-constructed from the underlying view. Example // Run this code #include <iomanip> #include <iostream> #include <ranges> #include <string_view> int main() { constexpr std::string_view keywords{"this throw true try typedef typeid"}; std::ranges::split_view split_view{keywords, ' '}; std::cout << "base() = " << std::quoted(split_view.base()) << "\n" "substrings: "; for (auto split : split_view) std::cout << std::quoted(std::string_view{split}) << ' '; std::cout << '\n'; } Output: base() = "this throw true try typedef typeid" substrings: "this" "throw" "true" "try" "typedef" "typeid" Defect reports The following behavior-changing defect reports were applied retroac- tively to previously published C++ standards. DR Applied to Behavior as published Correct behavior LWG 3590 C++20 the const& overload additionally required constraints relaxed validity of copy-assignment See also base returns a copy of the underlying (adapted) view (C++20) (public member function of std::ranges::lazy_split_view<V,Pattern>) http://cppreference.com 2024.06.10 std::ranges...t_view::base(3)
