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.

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

hash a JSON value

The hash function tries to rely on std::hash where possible. Furthermore, the type of the JSON value is taken into account to have different hash values for null, 0, 0U, and false, etc.

Template Parameters

BasicJsonType

Parameters

j	JSON value to hash

Returns

hash value of j

operator<()

bool nlohmann::json_abi_v3_11_3::detail::operator< ( const value_t  lhs, const value_t  rhs  )

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.

replace_substring()

template<typename StringType >

void nlohmann::json_abi_v3_11_3::detail::replace_substring ( StringType &  s, const StringType &  f, const StringType &  t  )

inline

replace all occurrences of a substring by another string

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 >

char * nlohmann::json_abi_v3_11_3::detail::to_chars ( char *  first, const char *  last, FloatType  value  )

private

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.
