# <small>nlohmann::basic_json::</small>rend
|
|
|
|
```cpp
|
|
reverse_iterator rend() noexcept;
|
|
const_reverse_iterator rend() const noexcept;
|
|
```
|
|
|
|
Returns an iterator to the reverse-end; that is, one before the first element. This element acts as a placeholder,
|
|
attempting to access it results in undefined behavior.
|
|
|
|
|
|
|
|
## Return value
|
|
|
|
reverse iterator to the element following the last element
|
|
|
|
## Exception safety
|
|
|
|
No-throw guarantee: this member function never throws exceptions.
|
|
|
|
## Complexity
|
|
|
|
Constant.
|
|
|
