the JSON type enumeration

This enumeration collects the different JSON types. It is internally used to distinguish the stored values, and the functions basic_json::is_null(), basic_json::is_object(), basic_json::is_array(), basic_json::is_string(), basic_json::is_boolean(), basic_json::is_number() (with basic_json::is_number_integer(), basic_json::is_number_unsigned(), and basic_json::is_number_float()), basic_json::is_discarded(), basic_json::is_primitive(), and basic_json::is_structured() rely on it.

Note: There are three enumeration entries (number_integer, number_unsigned, and number_float), because the library distinguishes these three types for numbers: basic_json::number_unsigned_t is used for unsigned integers, basic_json::number_integer_t is used for signed integers, and basic_json::number_float_t is used for floating-point numbers or to approximate integers which do not fit in the limits of their respective type.

See also: basic_json::basic_json(const value_t value_type) – create a JSON value with the default value for a given type

Since: version 1.0.0

◆ operator<()

bool nlohmann::detail::operator<	(	const value_t	lhs,

inlinenoexcept

comparison operator for JSON types

Returns an ordering that is similar to Python:

order: null < boolean < number < object < array < string < binary
furthermore, each type is not smaller than itself
discarded values are not comparable
binary is represented as a b"" string in python and directly comparable to a string; however, making a binary array directly comparable with a string would be surprising behavior in a JSON file.

template<typename FloatType >

JSON_HEDLEY_RETURNS_NON_NULL char * nlohmann::detail::to_chars	(	char *	first,
		const char *	last,
		FloatType	value
	)

generates a decimal representation of the floating-point number value in [first, last).

The format of the resulting decimal representation is similar to printf's g format. Returns an iterator pointing past-the-end of the decimal representation.

Note: The input number must be finite, i.e. NaN's and Inf's are not supported.; The buffer must be large enough.; The result is NOT null-terminated.
