# <small>nlohmann::json_pointer::</small>to_string
|
|
|
|
```cpp
|
|
string_t to_string() const;
|
|
```
|
|
|
|
Return a string representation of the JSON pointer.
|
|
|
|
## Return value
|
|
|
|
A string representation of the JSON pointer
|
|
|
|
## Exception safety
|
|
|
|
Strong exception safety: if an exception occurs, the original value stays intact.
|
|
|
|
## Complexity
|
|
|
|
Linear in the total length of the reference tokens.
|
|
|
|
## Notes
|
|
|
|
For each JSON pointer `ptr`, it holds:
|
|
|
|
```cpp
|
|
ptr == json_pointer(ptr.to_string());
|
|
```
|
|
|
|
## Examples
