std::ranges::join_view<V>::sentinel
|
template< bool Const >
class /*sentinel*/ |
(since C++20) (exposition only*) |
|
The return type of join_view::end when either of the underlying ranges (V or ranges::range_reference_t<V>) is not a common_range, or when the parent join_view is not a forward_range.
If V is not a simple view, Const is true for sentinels returned from the const overloads, and false otherwise. If V is a simple view, Const is true.
Typical implementation holds only one data member:
end_(exposition only*) - A sentinel obtained from (possibly const-qualified)V.
