.Sh DESCRIPTION
|
|
The
|
|
.Nm prop_object
|
|
family of functions operate on all property container object types.
|
|
.Bl -tag -width ""
|
|
.It Fn prop_object_retain "prop_object_t obj"
|
|
Increment the reference count on an object.
|
|
.It Fn prop_object_release "prop_object_t obj"
|
|
Decrement the reference count on an object.
|
|
If the last reference is dropped, the object is freed.
|
|
.It Fn prop_object_type "prop_object_t obj"
|
|
Determine the type of the object. Objects are one of the following types:
|
|
.Pp
|
|
.Bl -tag -width "PROP_TYPE_DICT_KEYSYM" -compact
|
|
.It Dv PROP_TYPE_BOOL
|
|
Boolean value
|
|
.Pq prop_bool_t
|
|
.It Dv PROP_TYPE_NUMBER
|
|
Number
|
|
.Pq prop_number_t
|
|
.It Dv PROP_TYPE_STRING
|
|
String
|
|
.Pq prop_string_t
|
|
.It Dv PROP_TYPE_DATA
|
|
Opaque data
|
|
.Pq prop_data_t

|
If
|
|
.Fa obj
|
|
is
|
|
.Dv NULL ,
|
|
then
|
|
.Dv PROP_TYPE_UNKNOWN
|
|
is returned.
|
|
.It Fn prop_object_equals "prop_object_t obj1" "prop_object_t obj2"
|
|
Returns
|
|
.Dv true
|
|
if the two objects are of the same type and are equivalent.
|
|
.It Fn prop_object_iterator_next "prop_object_iterator_t iter"
|
|
Return the next object in the collection
|
|
.Pq array or dictionary
|
|
being iterated by the iterator
|
|
.Fa iter .
|
|
If there are no more objects in the collection,
|
|
.Dv NULL
|
|
is returned.
|
|
.It Fn prop_object_iterator_reset "prop_object_iterator_t iter"
|
|
Reset the iterator to the first object in the collection being iterated
|
|
by the iterator
|
|
.Fa iter .
|
|
.It Fn prop_object_iterator_release "prop_object_iterator_t iter"
|
|
Release the iterator
