The type for RygelSearchExpression.

the RygelSearchExpression instance |
struct RygelSearchExpression { GTypeInstance parent_instance; volatile int ref_count; RygelSearchExpressionPrivate * priv; gpointer op; gpointer operand1; gpointer operand2; };
Represents a SearchExpression tree.
gpointer rygel_search_expression_ref (gpointer instance
);
Increases the reference count of object
.
|
a RygelSearchExpression. |
Returns : |
the same object
|
void rygel_search_expression_unref (gpointer instance
);
Decreases the reference count of object
. When its reference count drops to 0, the object is finalized (i.e. its memory is freed).

GParamSpec * rygel_param_spec_search_expression (const gchar *name

Creates a new GParamSpecBoxed instance specifying a RYGEL_TYPE_SEARCH_EXPRESSION
derived property.
See

void rygel_value_set_search_expression (GValue *value
,gpointer v_object
);
Set the contents of a RYGEL_TYPE_SEARCH_EXPRESSION
derived GValue to v_object
.
increases the reference count of rygel_value_set_search_expression()
v_object
(the GValue holds a reference to v_object
). If you do not wish to increase the reference count of the object (i.e. you wish to pass your current reference to the GValue because you no longer need it), use
instead.
rygel_value_take_search_expression()
It is important that your GValue holds a reference to v_object
(either its own, or one it has taken) to ensure that the object won't be destroyed while the GValue still exists).
|
a valid GValue of RYGEL_TYPE_SEARCH_EXPRESSION derived type |
|
object value to be set |
gpointer rygel_value_get_search_expression (const GValue *value
);
Get the contents of a RYGEL_TYPE_SEARCH_EXPRESSION
derived GValue.
|
a valid GValue of RYGEL_TYPE_SEARCH_EXPRESSION derived type |
Returns : |
object contents of value
|
void rygel_value_take_search_expression (GValue *value
,gpointer v_object
);
Sets the contents of a RYGEL_TYPE_SEARCH_EXPRESSION
derived GValue to v_object
and takes over the ownership of the callers reference to v_object
; the caller doesn't have to unref it any more (i.e. the reference count of the object is not increased).
If you want the GValue to hold its own reference to v_object
, use
instead.
