Method
TsparqlNotifiersignal_subscribe
Declaration [src]
guint
tracker_notifier_signal_subscribe (
TrackerNotifier* notifier,
GDBusConnection* connection,
const gchar* service,
const gchar* object_path,
const gchar* graph
)
Description [src]
Listens to notification events from a remote DBus SPARQL endpoint.
If connection
refers to a message bus (system/session), service
must refer
to a D-Bus name (either unique or well-known). If connection
is a non-message
bus (e.g. a peer-to-peer D-Bus connection) the service
argument may be NULL
.
If the object_path
argument is NULL
, the default
/org/freedesktop/Tracker3/Endpoint
path will be
used. If graph
is NULL
, all graphs will be listened for.
The signal subscription can be removed with
tracker_notifier_signal_unsubscribe()
.
Note that this call is not necessary to receive notifications on
a connection obtained through tracker_sparql_connection_bus_new()
,
only to listen to update notifications from additional DBus endpoints.
