Functions

rygel_search_expression_satisfied_by ()

gboolean
rygel_search_expression_satisfied_by (RygelSearchExpression *self,
                                      RygelMediaObject *media_object);

Parameters

self

the RygelSearchExpression instance

 

media_object

 

 

rygel_search_expression_to_string ()

gchar *
rygel_search_expression_to_string (RygelSearchExpression *self);

Parameters

self

the RygelSearchExpression instance

 

rygel_search_expression_ref ()

gpointer
rygel_search_expression_ref (gpointer instance);

Increases the reference count of object .

Parameters

instance

a RygelSearchExpression.

 

Returns

the same object


rygel_search_expression_unref ()

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).

Parameters

instance

a RygelSearchExpression.

 

rygel_param_spec_search_expression ()

GParamSpec *
rygel_param_spec_search_expression (const gchar *name,
                                    const gchar *nick,
                                    const gchar *blurb,
                                    GType object_type,
                                    GParamFlags flags);

Creates a new GParamSpecBoxed instance specifying a RYGEL_TYPE_SEARCH_EXPRESSION derived property.

See g_param_spec_internal() for details on property names.

Parameters

name

canonical name of the property specified

 

nick

nick name for the property specified

 

blurb

description of the property specified

 

object_type

RYGEL_TYPE_SEARCH_EXPRESSION derived type of this property  

flags

flags for the property specified

 

rygel_value_set_search_expression ()

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 .

rygel_value_set_search_expression() increases the reference count of 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 rygel_value_take_search_expression() instead.

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).

Parameters

value

a valid GValue of RYGEL_TYPE_SEARCH_EXPRESSION derived type

 

v_object

object value to be set

 

rygel_value_get_search_expression ()

gpointer
rygel_value_get_search_expression (const GValue *value);

Get the contents of a RYGEL_TYPE_SEARCH_EXPRESSION derived GValue.

Parameters

value

a valid GValue of RYGEL_TYPE_SEARCH_EXPRESSION derived type

 

Returns

object contents of value


rygel_value_take_search_expression ()

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 rygel_value_set_search_expression() instead.

Parameters

value

a valid GValue of RYGEL_TYPE_SEARCH_EXPRESSION derived type

 

v_object

object value to be set
