Helper to determine whether there's a key_type for T.

This helper is used to tell associative containers apart from other containers such as sequence containers. For instance, std::map passes the test as it contains a mapped_type, whereas std::vector fails the test.

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]	s	a string representation of a JSON object
[in]	n	the length of string s

Returns: a JSON object

Since: version 1.0.0

Definition at line 17252 of file json.hpp.

nlohmann::json::json_pointer operator""_json_pointer	(	const char *	s,

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]	s	a string representation of a JSON Pointer
[in]	n	the length of string s

Returns: a JSON pointer object
