std::ranges::join_view<V>::iterator
|
(since C++20) (exposition only*) |
The return type of join_view::begin, and of join_view::end when both the outer range V and the inner range ranges::range_reference_t<V> satisfy common_range and the parent join_view is a forward_range.
If V is not a simple view (e.g. if ranges::iterator_t<const V> is invalid or different from ranges::iterator_t<V>), Const is true for iterators returned from the const overloads, and false otherwise. If V is a simple view, Const is true if and only if ranges::range_reference_t<V> is a reference.

Member functions
|
(C++20)
|
constructs an iterator (public member function) |
|
(C++20)
|
accesses the element (public member function) |
|
(C++20)
|
advances or decrements the underlying iterators (public member function) |
|
(C++20)
|
skips over empty inner ranges (exposition-only member function*) |
Non-member functions
|
(C++20)
|
compares the underlying iterators (function) |
|
(C++20)
|
casts the result of dereferencing the underlying iterator to its associated rvalue reference type (function) |
|
(C++20)
|
swaps the objects pointed to by two underlying iterators (function) |
