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>

...

Added in version 3.11.3.
