Class
TsparqlEndpointDBus
Description [src]
final class Tsparql.EndpointDBus : Tsparql.Endpoint
implements Gio.Initable {
/* No available fields */
}
TrackerEndpointDBus
makes the RDF data in a TrackerSparqlConnection
accessible to other processes via DBus.
This object is a TrackerEndpoint
subclass that exports
a TrackerSparqlConnection
so its RDF data is accessible to other
processes through the given GDBusConnection
.
// This process already has org.example.Endpoint bus name
endpoint = tracker_endpoint_dbus_new (sparql_connection,
dbus_connection,
NULL,
NULL,
&error);
// From another process
connection = tracker_sparql_connection_bus_new ("org.example.Endpoint",
NULL,
dbus_connection,
&error);
The TrackerEndpointDBus
will manage a DBus object at the given path
with the org.freedesktop.Tracker3.Endpoint
interface, if no path is
given the object will be at the default /org/freedesktop/Tracker3/Endpoint
location.
Access to D-Bus endpoints may be managed via the
TrackerEndpointDBus::block-call
signal, the boolean
return value expressing whether the request is blocked or not.
Inspection of the requester address is left up to the user. The
default value allows all requests independently of their provenance.
However, moderating access to D-Bus interfaces is typically not necessary in user code, as access to public D-Bus endpoints will be transparently managed through the Tracker portal service for applications sandboxed via XDG portals. These already have access to D-Bus SPARQL endpoints and their data naturally filtered as defined in the application manifest.
A TrackerEndpointDBus
may be created on a different thread/main
context from the one that created TrackerSparqlConnection
.
Constructors
tracker_endpoint_dbus_new
Registers a Tracker endpoint object at object_path
on dbus_connection
.
The default object path is /org/freedesktop/Tracker3/Endpoint
.
Instance methods
Methods inherited from TrackerEndpoint (7)
tracker_endpoint_get_allowed_graphs
Returns the list of RDF graphs that the endpoint allows access for.
since: 3.7
tracker_endpoint_get_allowed_services
Returns the list of external SPARQL endpoints that are allowed to be accessed through this endpoint.
since: 3.7
tracker_endpoint_get_readonly
Returns whether the endpoint is readonly, thus SPARQL update queries are disallowed.
since: 3.7
tracker_endpoint_get_sparql_connection
Returns the TrackerSparqlConnection
that this endpoint proxies
to a wider audience.
tracker_endpoint_set_allowed_graphs
Sets the list of RDF graphs that this endpoint will allow access
for. Any explicit (e.g. GRAPH
keyword) or implicit (e.g. through the
default anonymous graph) access to RDF graphs unespecified in this
list in SPARQL queries will be seen as if those graphs did not exist, or
(equivalently) had an empty set. Changes to these graphs through SPARQL
updates will also be disallowed.
since: 3.7
tracker_endpoint_set_allowed_services
Sets the list of external SPARQL endpoints that this endpoint
will allow access for. Access through the SERVICE
SPARQL syntax
will fail for services not specified in this list.
since: 3.7
tracker_endpoint_set_readonly
Sets whether the endpoint will be readonly. Readonly endpoints
will not allow SPARQL update queries. The underlying
TrackerSparqlConnection
may be readonly of its own, this
method does not change its behavior in any way.
since: 3.7
Methods inherited from GInitable (1)
g_initable_init
Initializes the object implementing the interface.
