◆ value_t

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: see 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

Enumerator
null	null value
object	object (unordered set of name/value pairs)
array	array (ordered collection of values)
string	string value
boolean	boolean value
number_integer	number value (signed integer)
number_unsigned	number value (unsigned integer)
number_float	number value (floating-point)
binary	binary array (ordered collection of bytes)
discarded	discarded by the parser callback function

Template Parameters

Parameters

j	JSON value to hash

Returns: hash value of j

bool detail::operator<	(	const value_t	lhs,

noexcept

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.

◆ replace_substring()

template<typename StringType >

void detail::replace_substring	(	StringType &	s,

Parameters

[in,out]	s	the string to manipulate; changed so that all occurrences of f are replaced with t
[in]	f	the substring to replace with t
[in]	t	the string to replace f

Precondition: The search string f must not be empty. This precondition is enforced with an assertion.

◆ to_chars()

template<typename FloatType >

JSON_HEDLEY_RETURNS_NON_NULL char * detail::to_chars	(	char *	first,

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.
