std::ranges::lazy_split_view<V, Pattern>::outer_iterator<Const>::value_type

struct value_type : ranges::view_interface<value_type>
 (since C++20)

The value type of the iterator ranges::lazy_split_view<V, Pattern>::/*outer_iterator*/<Const>.

Data members

Typical implementations of value_type hold only one non-static data member: an iterator of type outer_iterator (shown here as i_ for exposition only) into underlying view of the outer class.

Member functions

(constructor)
(C++20)
 constructs a value_type object
(public member function)
begin
(C++20)
 returns an inner_iterator to the beginning of the inner range
(public member function)
end
(C++20)
 returns a std::default_sentinel
(public member function)
Inherited from std::ranges::view_interface
(C++20)
 returns whether the derived view is empty. Provided if it satisfies sized_range or forward_range.
(public member function of std::ranges::view_interface<D>)
(C++23)
 returns a constant iterator to the beginning of the range.
(public member function of std::ranges::view_interface<D>)
(C++23)
 returns a sentinel for the constant iterator of the range.
(public member function of std::ranges::view_interface<D>)
(C++20)
 returns whether the derived view is not empty. Provided if ranges::empty is applicable to it.
(public member function of std::ranges::view_interface<D>)
(C++20)
 returns the first element in the derived view. Provided if it satisfies forward_range.
(public member function of std::ranges::view_interface<D>)

Member functions

std::ranges::lazy_split_view::outer_iterator::value_type::value_type

value_type() = default;
 (1) (since C++20) 
constexpr explicit value_type(/*outer_iterator*/ i);
 (2) (since C++20)
1) Value initializes the exposition-only non-static data member i_ via its default member initializer (= /*outer_iterator*/()).
2) Initializes i_ with std::move(i).

std::ranges::lazy_split_view::outer_iterator::value_type::begin

constexpr /*inner_iterator*/<Const> begin() const;
 (since C++20)

Equivalent to return /*inner_iterator*/<Const>{i_};.

std::ranges::lazy_split_view::outer_iterator::value_type::end

constexpr std::default_sentinel_t end() const noexcept;
 (since C++20)

Returns std::default_sentinel.
