Method

TsparqlSparqlConnectiondeserialize_async

since: 3.4

Declaration [src] 

void
tracker_sparql_connection_deserialize_async (
  TrackerSparqlConnection* connection,
  TrackerDeserializeFlags flags,
  TrackerRdfFormat format,
  const gchar* default_graph,
  GInputStream* stream,
  GCancellable* cancellable,
  GAsyncReadyCallback callback,
  gpointer user_data
)

Description [src]

Loads the RDF data contained in stream into the given connection.

This is an asynchronous operation, callback will be invoked when the data has been fully inserted to connection.

The RDF data will be inserted in the given default_graph if one is provided, or the anonymous graph if default_graph is NULL. Any RDF data that has a graph specified (e.g. using the GRAPH clause in the Trig format) will be inserted in the specified graph instead of default_graph.

The flags argument is reserved for future expansions, currently TRACKER_DESERIALIZE_FLAGS_NONE must be passed.

Available since: 3.4

This method completes asynchronously. Use tracker_sparql_connection_deserialize_finish() inside the GAsyncReadyCallback to obtain the result of the operation.
