Returns a copy of the underlying view _[base](../lazy%5Fsplit%5Fview.html#base "cpp/ranges/lazy split view")_.

1. Copy constructs the result from the underlying view _base_.

2. Move constructs the result from the underlying view _base_.

[edit] Return value

A copy of the underlying view _[base](../lazy%5Fsplit%5Fview.html#base "cpp/ranges/lazy split view")_.

[edit] Example

#include #include #include   void print(std::string_view rem, auto const& r, std::string_view post = "\n") { for (std::cout << rem; auto const& e : r) std::cout << e; std::cout << post; }   int main() { constexpr std::string_view keywords{ "this,..throw,..true,..try,.." }; constexpr std::string_view pattern{",.."}; constexpr std::ranges::lazy_split_view lazy_split_view{keywords, pattern}; print("base() = [", lazy_split_view.base(), "]\n" "substrings: "); for (auto const& split: lazy_split_view) print("[", split, "] "); }

Output:

base() = [this,..throw,..true,..try,..] substrings: [this] [throw] [true] [try] []
