106 : @brief the JSON type enumeration
107 :
108 : This enumeration collects the different JSON types. It is internally used to
109 : distinguish the stored values, and the functions @ref basic_json::is_null(),
110 : @ref basic_json::is_object(), @ref basic_json::is_array(),
111 : @ref basic_json::is_string(), @ref basic_json::is_boolean(),
112 : @ref basic_json::is_number() (with @ref basic_json::is_number_integer(),
113 : @ref basic_json::is_number_unsigned(), and @ref basic_json::is_number_float()),
114 : @ref basic_json::is_discarded(), @ref basic_json::is_primitive(), and
115 : @ref basic_json::is_structured() rely on it.
116 :
117 : @note There are three enumeration entries (number_integer, number_unsigned, and
118 : number_float), because the library distinguishes these three types for numbers:
119 : @ref basic_json::number_unsigned_t is used for unsigned integers,
120 : @ref basic_json::number_integer_t is used for signed integers, and
121 : @ref basic_json::number_float_t is used for floating-point numbers or to
122 : approximate integers which do not fit in the limits of their respective type.
123 :
124 : @sa see @ref basic_json::basic_json(const value_t value_type) -- create a JSON
125 : value with the default value for a given type
