Classes

Batch	`TrackerBatch` executes a series of SPARQL updates and RDF data insertions within a transaction. since: 3.1
Endpoint	`TrackerEndpoint` is a helper object to make RDF triple stores represented by a `TrackerSparqlConnection` publicly available to other processes/hosts.
EndpointDBus	`TrackerEndpointDBus` makes the RDF data in a `TrackerSparqlConnection` accessible to other processes via DBus.
EndpointHttp	`TrackerEndpointHttp` makes the RDF data in a `TrackerSparqlConnection` accessible to other hosts via HTTP. since: 3.1
NamespaceManager	`TrackerNamespaceManager` object represents a mapping between namespaces and their shortened prefixes.
Notifier	`TrackerNotifier` allows receiving notification on changes in the data stored by a `TrackerSparqlConnection`.
Resource	`TrackerResource` is an in-memory representation of RDF data about a given resource.
SparqlConnection	`TrackerSparqlConnection` holds a connection to a RDF triple store.
SparqlCursor	`TrackerSparqlCursor` provides the methods to iterate the results of a SPARQL query.
SparqlStatement	`TrackerSparqlStatement` represents a prepared statement for a SPARQL query.

Structs

NotifierEvent

The TrackerNotifierEvent struct represents a change event in the stored data.

Enumerations

DeserializeFlags	Flags affecting deserialization from a RDF data format.
NotifierEventType	Notifier event types.
RdfFormat	Describes a RDF format to be used in data exchange.
SerializeFlags	Flags affecting serialization into a RDF data format.
SparqlValueType	Enumeration with the possible types of the cursor’s cells.

Bitfields

SparqlConnectionFlags

Connection flags to modify TrackerSparqlConnection behavior.

Error Domains

SparqlError

Error domain for Tracker Sparql. Errors in this domain will be from the TrackerSparqlError enumeration. See GError for more information on error domains.

Functions

check_version	Checks that the Tracker library in use is compatible with the given version.
sparql_escape_string	Escapes `literal` so it is suitable for insertion in SPARQL queries as string literals.
sparql_escape_uri	Escapes a string for use as a URI.
sparql_escape_uri_printf	Formats and escapes a string for use as a URI. This function takes variadic arguments.
sparql_escape_uri_vprintf	Formats and escapes a string for use as a URI. This function takes a `va_list`.
sparql_get_ontology_nepomuk	Returns a path to the built-in Nepomuk ontologies.
sparql_get_uuid_urn	Creates a fresh UUID-based URN.

Function Macros

CHECK_VERSION

This macro essentially does the same thing as tracker_check_version() but as a pre-processor operation rather than a run-time operation. It will evaluate true or false based the version passed in and the version available.
