返回底层视图
base_
的副本。
1)
从底层视图
base_
复制构造结果。
2)
从底层视图
base_
移动构造结果。
返回值
底层视图
base_
的一个副本。
示例
运行此代码
#include <iostream> #include <ranges> #include <string_view> 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, "] "); }
输出:
base() = [this,..throw,..true,..try,..] substrings: [this] [throw] [true] [try] []
