std::ranges::lazy_split_view<V,Pattern>::base
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
#include <iostream>
#include <ranges>
#include <string_view>
// A temporary patch until P2210R2 is implemented
#define lazy_split_view split_view
#define lazy_split split
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]
