DESCRIPTION
Theprop_object
family of functions operate on all
property container object types.
prop_object_retain
(prop_object_t obj)- Increment the reference count on an object.
prop_object_release
(prop_object_t obj)- Decrement the reference count on an object. If the last reference is dropped, the object is freed.
prop_object_type
(prop_object_t obj)- Determine the type of the object. Objects are one of the following types:
PROP_TYPE_BOOL
- Boolean value (prop_bool_t)
PROP_TYPE_NUMBER
- Number (prop_number_t)
PROP_TYPE_STRING
- String (prop_string_t)
PROP_TYPE_DATA
- Opaque data (prop_data_t)
PROP_TYPE_ARRAY
- Array (prop_array_t)
PROP_TYPE_DICTIONARY
- Dictionary (prop_dictionary_t)
PROP_TYPE_DICT_KEYSYM
- Dictionary key symbol (prop_dictionary_keysym_t)
If obj is
NULL
, thenPROP_TYPE_UNKNOWN
is returned. prop_object_equals
(prop_object_t obj1, prop_object_t obj2)- Returns
true
if the two objects are of the same type and are equivalent. prop_object_iterator_next
(prop_object_iterator_t iter)- Return the next object in the collection (array or dictionary) being
iterated by the iterator iter. If there are no more
objects in the collection,
NULL
is returned. prop_object_iterator_reset
(prop_object_iterator_t iter)- Reset the iterator to the first object in the collection being iterated by the iterator iter.
prop_object_iterator_release
(prop_object_iterator_t iter)- Release the iterator iter.
