The name `ranges::cend` denotes a customization point object
|
| 4 |
+
[[customization.point.object]]. Given a subexpression `E` with type `T`,
|
| 5 |
+
let `t` be an lvalue that denotes the reified object for `E`. Then:
|
| 6 |
|
| 7 |
+
- If `E` is an rvalue and `enable_borrowed_range<remove_cv_t<T>>` is
|
| 8 |
+
`false`, `ranges::cend(E)` is ill-formed.
|
| 9 |
+
- Otherwise, let `U` be `ranges::end(possibly-const-range(t))`.
|
| 10 |
+
`ranges::cend(E)` is expression-equivalent to
|
| 11 |
+
`const_sentinel<decltype(U)>(U)`.

[*Note 1*: Whenever `ranges::cend(E)` is a valid expression, the types
|
| 14 |
+
`S` and `I` of the expressions `ranges::cend(E)` and `ranges::cbegin(E)`
|
| 15 |
+
model `sentinel_for<S, I>`. If `S` models `input_iterator`, then `S`
|
| 16 |
+
also models *`constant-iterator`*. — *end note*]
