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.

◆ JSON_HEDLEY_NON_NULL()

template<typename FloatType >
nlohmann::detail::JSON_HEDLEY_NON_NULL ( 1  ,
2   
)

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.

◆ little_endianess()

static bool nlohmann::detail::little_endianess ( int  num = 1)
inlinestaticnoexcept

determine system byte order

Returns
true if and only if system's byte order is little endian

◆ operator<()

bool nlohmann::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.
