# JSON_HAS_STATIC_RTTI
|
|
|
|
```
|
|
#define JSON_HAS_STATIC_RTTI /* value */
|
|
```
|
|
|
|
This macro indicates whether the standard library has any support for RTTI (run time type information). Possible values are `1` when supported or `0` when unsupported.
|
|
|
|
## Default definition
|
|
|
|
The default value is detected based on the preprocessor macro `_HAS_STATIC_RTTI`.
|
|
|
|
When the macro is not defined, the library will define it to its default value.
|
|
|
|
## Examples

Example
|
|

The code below forces the library to enable support for libraries with RTTI dependence:
|
|
|
|
```
|
|
#define JSON_HAS_STATIC_RTTI 1
|
|
#include <nlohmann/json.hpp>
|
|
|
|
...
|
|
```
