NAME¶

std::ranges::lazy_split_view::base - std::ranges::lazy_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.

1) Copy constructs the result from the underlying view.
2) Move constructs the result from the underlying view.

Parameters¶

(none)

Return value¶

A copy of the underlying view.

Example¶

// Run this code

#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, "] ");
}

Output:¶

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