tracker_resource_set_gvalue ()

void
tracker_resource_set_gvalue (TrackerResource *self,
                             const char *property_uri,
                             const GValue *value);

State that the only value for the given property is 'value'. Any existing values for 'property' will be removed.

When serialising to SPARQL, any properties that were set with this function will get a corresponding DELETE statement to remove any existing values in the database.

You can pass any kind of GValue for value , but serialization functions will normally only be able to serialize URIs/relationships and fundamental value types (string, int, etc.).

Since: 1.10

tracker_resource_set_identifier ()

void
tracker_resource_set_identifier (TrackerResource *self,
                                 const char *identifier);

Changes the identifier of a TrackerResource. The identifier should be a URI or compact URI, but this is not necessarily enforced. Invalid identifiers may cause errors when serializing the resource or trying to insert the results in a database.

If the identifier is set to NULL, a SPARQL blank node identifier such as "_:123" is assigned to the resource.

                                    const char *property_uri,
