NAME¶

std::ranges::chunk_view::outer-iterator::value_type - std::ranges::chunk_view::outer-iterator::value_type

Synopsis¶

Defined in header <ranges>
struct value_type : view_interface<value_type> (since C++23)

A value type of the iterator chunk_view::outer-iterator, formed when V models
input_range.

Member functions¶

constructor constructs an value_type
(C++23) (public member function)
begin returns the beginning chunk_view::inner-iterator
(C++23) (public member function)
end returns the default sentinel
(C++23) (public member function)
size returns the size of the view
(C++23) (public member function)
Inherited from std::ranges::view_interface
empty returns whether the derived view is empty. Provided if it satisfies
(C++20) sized_range or forward_range.
(public member function of std::ranges::view_interface<D>)
cbegin returns a constant iterator to the beginning of the range.
(C++23) (public member function of std::ranges::view_interface<D>)
cend returns a sentinel for the constant iterator of the range.
(C++23) (public member function of std::ranges::view_interface<D>)
operator bool returns whether the derived view is not empty. Provided if
(C++20) ranges::empty is applicable to it.
(public member function of std::ranges::view_interface<D>)

std::ranges::chunk_view::outer-iterator::value_type::value_type

private:

// exposition only (since C++23)

constexpr explicit value_type( chunk_view& parent );

Constructs the value_type object so that parent_ is initialized with
std::addressof(parent).

Parameters¶

parent - the chunk_view object

std::ranges::chunk_view::outer-iterator::value_type::begin

constexpr /*inner-iterator*/ begin() const noexcept; (since C++23)

Equivalent to return /*inner-iterator*/(*parent_);.

std::ranges::chunk_view::outer-iterator::value_type::end

constexpr std::default_sentinel_t end() const noexcept; (since C++23)

Equivalent to return std::default_sentinel;.

std::ranges::chunk_view::outer-iterator::value_type::size

constexpr auto size() const
requires std::sized_sentinel_for<ranges::sentinel_t<V>, (since C++23)
ranges::iterator_t<V>>;

Returns the size of the view.

Equivalent to
return /*to-unsigned-like*/(
ranges::min(parent_->remainder_, ranges::end(parent_->base_) -
*parent_->current_));
