Function Documentation

int json_object_array_add	(	struct json_object *	obj,
		struct json_object *	val
	)

Add an element to the end of a json_object of type json_type_array

The reference count will not be incremented. This is to make adding fields to objects in code more compact. If you want to retain a reference to an added object you must wrap the passed object with json_object_get

Parameters

obj	the json_object instance
val	the json_object to be added

Definition at line 522 of file json_object.c.

struct json_object* json_object_array_get_idx	(	struct json_object *	obj,
		int	idx
	)

Get the element at specificed index of the array (a json_object of type json_type_array)

Parameters

obj	the json_object instance
idx	the index to get the element at

Returns: the json_object at the specified index (or NULL)

Definition at line 535 of file json_object.c.

int json_object_array_length ( struct json_object * obj )

Get the length of a json_object of type json_type_array

Parameters

obj	the json_object instance

Returns: an int

Definition at line 516 of file json_object.c.

int json_object_array_put_idx	(	struct json_object *	obj,
		int	idx,
		struct json_object *	val
	)

Insert or replace an element at a specified index in an array (a json_object of type json_type_array)

The reference count will not be incremented. This is to make adding fields to objects in code more compact. If you want to retain a reference to an added object you must wrap the passed object with json_object_get

The reference count of a replaced object will be decremented.

The array size will be automatically be expanded to the size of the index if the index is larger than the current size.

Parameters

obj	the json_object instance
idx	the index to insert the element at
val	the json_object to be added

Definition at line 528 of file json_object.c.

struct json_object* json_object_get ( struct json_object * obj )

Increment the reference count of json_object

Parameters

obj	the json_object instance

struct array_list* json_object_get_array ( struct json_object * obj )

Get the arraylist of a json_object of type json_type_array

Parameters

obj	the json_object instance

Returns: an arraylist

Definition at line 505 of file json_object.c.

boolean json_object_get_boolean ( struct json_object * obj )

Get the boolean value of a json_object

The type is coerced to a boolean if the passed object is not a boolean. integer and double objects will return FALSE if there value is zero or TRUE otherwise. If the passed object is a string it will return TRUE if it has a non zero length. If any other object type is passed TRUE will be returned if the object is not NULL.

Parameters

obj	the json_object instance

Returns: a boolean

Definition at line 306 of file json_object.c.

double json_object_get_double ( struct json_object * obj )

Get the double value of a json_object

The type is coerced to a double if the passed object is not a double. integer objects will return their dboule conversion. Strings will be parsed as a double. If no conversion exists then 0.0 is returned.

Parameters

obj	the json_object instance

Returns: an double

Definition at line 395 of file json_object.c.

int json_object_get_int ( struct json_object * obj )

Get the int value of a json_object

The type is coerced to a int if the passed object is not a int. double objects will return their integer conversion. Strings will be parsed as an integer. If no conversion exists then 0 is returned.

Parameters

obj	the json_object instance

Returns: an int

Definition at line 341 of file json_object.c.

struct lh_table* json_object_get_object ( struct json_object * obj )

Get the hashtable of a json_object of type json_type_object

obj	the json_object instance

Returns: a linkhash

Definition at line 259 of file json_object.c.

char* json_object_get_string ( struct json_object * obj )

Get the string value of a json_object

If the passed object is not of type json_type_string then the JSON representation of the object is returned.

The returned string memory is managed by the json_object and will be freed when the reference count of the json_object drops to zero.

Parameters

obj	the json_object instance

Returns: a string

Definition at line 452 of file json_object.c.
