Method

TrackerSparqlConnectionupdate_resource

since: 3.1

Declaration [src]

gboolean
tracker_sparql_connection_update_resource (
  TrackerSparqlConnection* connection,
  const gchar* graph,
  TrackerResource* resource,
  GCancellable* cancellable,
  GError** error
)

Description [src]

Inserts a resource as described by resource on the given graph.

This method is synchronous and will block until the update is finished. See tracker_sparql_connection_update_resource_async() for an asynchronous variant.

It is recommented to consider the usage of TrackerBatch to cluster database updates. Frequent isolated SPARQL updates through this method will have a degraded performance in comparison.

Available since: 3.1

Parameters

Type: GError **

The return location for a recoverable error.

In case of error, the argument will be set to a newly allocated GError; the caller will take ownership of the data, and be responsible for freeing it.
