Function Documentation

◆ operator""_json()

nlohmann::json operator""_json ( const char *  s,
std::size_t  n 
)
inline

user-defined string literal for JSON values

This operator implements a user-defined string literal for JSON objects. It can be used by adding "_json" to a string literal and returns a JSON object if no parse error occurred.

Parameters
[in]sa string representation of a JSON object
[in]nthe length of string s
Returns
a JSON object
Since
version 1.0.0

Definition at line 20793 of file json.hpp.

◆ operator""_json_pointer()

nlohmann::json::json_pointer operator""_json_pointer ( const char *  s,
std::size_t  n 
)
inline

user-defined string literal for JSON pointer

This operator implements a user-defined string literal for JSON Pointers. It can be used by adding "_json_pointer" to a string literal and returns a JSON pointer object if no parse error occurred.

Parameters
[in]sa string representation of a JSON Pointer
[in]nthe length of string s
Returns
a JSON pointer object
Since
version 2.0.0

Definition at line 20811 of file json.hpp.
