Endpoint

TrackerEndpoint is a helper object to make RDF triple stores represented by a TrackerSparqlConnection publicly available to other processes/hosts.

since: 3.0

EndpointDBus

TrackerEndpointDBus makes the RDF data in a TrackerSparqlConnection accessible to other processes via DBus.

since: 3.0

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.

since: 3.0

Notifier

TrackerNotifier allows receiving notification on changes in the data stored by a TrackerSparqlConnection.

since: 3.0

Resource

TrackerResource is an in-memory representation of RDF data about a given resource.

since: 3.0

SparqlConnection

TrackerSparqlConnection holds a connection to a RDF triple store.

since: 3.0

SparqlCursor

TrackerSparqlCursor provides the methods to iterate the results of a SPARQL query.

since: 3.0

SparqlStatement

TrackerSparqlStatement represents a prepared statement for a SPARQL query.

since: 3.0

Structs

NotifierEvent

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

since: 3.0

Enumerations

DeserializeFlags

Flags affecting deserialization from a RDF data format.

since: 3.0

NotifierEventType

Notifier event types.

since: 3.0

RdfFormat

Describes a RDF format to be used in data exchange.

since: 3.0

SerializeFlags

Flags affecting serialization into a RDF data format.

since: 3.0

Enumeration with the possible types of the cursor’s cells.

since: 3.0

Bitfields

SparqlConnectionFlags

Connection flags to modify TrackerSparqlConnection behavior.

since: 3.0

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.

since: 3.0

Functions

check_version

Checks that the Tracker library in use is compatible with the given version.

since: 3.0

sparql_escape_string

Escapes literal so it is suitable for insertion in SPARQL queries as string literals.

since: 3.0

sparql_escape_uri

Escapes a string for use as a URI.

since: 3.0

sparql_escape_uri_printf

Formats and escapes a string for use as a URI. This function takes variadic arguments.

since: 3.0

sparql_escape_uri_vprintf
