NAME¶
std::ranges::lazy_split_view::end - std::ranges::lazy_split_view::end
Synopsis¶
constexpr auto end() requires ranges::forward_range<V>
&& (1) (since C++20)
ranges::common_range<V>;
constexpr auto end() const; (2) (since C++20)
1) Returns an iterator representing the end of the view.
Equivalent to:
return /*outer_iterator*/</*simple_view*/<V>>{*this,
ranges::end(base_)};.
2) Returns an outer_iterator or a std::default_sentinel representing the end
of the
view.
Equivalent to:
if constexpr (ranges::forward_range<V> &&
ranges::forward_range<const V> &&
ranges::common_range<const V>)
return /*outer_iterator*/<true>{*this, ranges::end(base_)};
else
return std::default_sentinel;
Parameters¶
(none)
Return value¶
An outer_iterator or a std::default_sentinel representing the end of the view.
Example¶
// Run this code
#include <iostream>
#include <ranges>
#include <string_view>
int main()
{
constexpr std::string_view keywords{ "false float for friend" };
std::ranges::lazy_split_view kw{ keywords, ' ' };
const auto count = std::ranges::distance(kw.begin(), kw.end());
std::cout << "Words count: " << count << '\n';
}
Output:¶
Words count: 4
