# std::ranges::join_with_view<V,Pattern>::sentinel

From cppreference.com
< cpp‎ | ranges‎ | join with view

template< bool Const > class /*sentinel*/ |  | (since C++23) (exposition only*)

The return type of `join_with_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_with_view` is not a `forward_range`.

If either `V` or `Pattern` is not a simple view, `Const` is true for sentinels returned from the const overloads, and false otherwise. If `V` and `Pattern` are simple views, `Const` is true.

### Member functions
