Method

TrackerSparqlStatementexecute_async

Declaration [src]

void
tracker_sparql_statement_execute_async (
  TrackerSparqlStatement* stmt,
  GCancellable* cancellable,
  GAsyncReadyCallback callback,
  gpointer user_data
)

Description [src]

Executes asynchronously the SELECT or ASK SPARQL query with the currently bound values.

This function also works for DESCRIBE and CONSTRUCT queries that retrieve data from the triple store. These query forms that return RDF data are however more useful together with tracker_sparql_statement_serialize_async().

This function should only be called on TrackerSparqlStatement objects obtained through tracker_sparql_connection_query_statement() or SELECT/CONSTRUCT/DESCRIBE statements loaded through tracker_sparql_connection_load_statement_from_gresource(). An error will be raised if this method is called on a INSERT or DELETE SPARQL query.

Parameters

`cancellable`	`GCancellable*`
	Optional `GCancellable`
	The argument can be `NULL`.
	The data is owned by the caller of the function.
`callback`	`GAsyncReadyCallback`
	User-defined Gio.AsyncReadyCallback to be called when the asynchronous operation is finished.
`user_data`	`gpointer`
	User-defined data to be passed to `callback`.
