Union Documentation

union json_value

a JSON value

The actual storage for a JSON value of the basic_json class. This union combines the different storage types for the JSON value types defined in value_t.

JSON type	value_t type	used type
object	object	pointer to object_t
array	array	pointer to array_t
string	string	pointer to string_t
boolean	boolean	boolean_t
number	number_integer	number_integer_t
number	number_unsigned	number_unsigned_t
number	number_float	number_float_t
null	null	no value is stored

Note

Variable-length types (objects, arrays, and strings) are stored as pointers. The size of the union should not exceed 64 bits if the default value types are used.
