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 |

(C++20)
|
Returns whether the derived view is empty. Provided if it satisfies forward_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> ) |

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
.
