TrackerSparqlCursor is an object which provides methods to iterate the results of a query to the Tracker Store.
TrackerSparqlConnection *
tracker_sparql_cursor_get_connection (TrackerSparqlCursor *cursor
);
Returns the TrackerSparqlConnection associated with this TrackerSparqlCursor.
the cursor TrackerSparqlConnection. The returned object must not be unreferenced by the caller.
[transfer none]
gint
tracker_sparql_cursor_get_n_columns (TrackerSparqlCursor *cursor
);
This method should only be called after a successful
tracker_sparql_cursor_next()
; otherwise its return value
will be undefined.
const gchar * tracker_sparql_cursor_get_string (TrackerSparqlCursor *cursor
,gint column
,glong *length
);
Retrieves a string representation of the data in the current
row in column
.
gboolean tracker_sparql_cursor_get_boolean (TrackerSparqlCursor *cursor
,gint column
);
Retrieve a boolean for the current row in column
.
gdouble tracker_sparql_cursor_get_double (TrackerSparqlCursor *cursor
,gint column
);
Retrieve a double for the current row in column
.
gint64 tracker_sparql_cursor_get_integer (TrackerSparqlCursor *cursor
,gint column
);
Retrieve an integer for the current row in column
.
TrackerSparqlValueType tracker_sparql_cursor_get_value_type (TrackerSparqlCursor *cursor
,gint column
);
The data type bound to the current row in column
is returned.
const gchar * tracker_sparql_cursor_get_variable_name (TrackerSparqlCursor *cursor
,gint column
);
Retrieves the variable name for the current row in column
.
void
tracker_sparql_cursor_close (TrackerSparqlCursor *cursor
);
Closes the iterator, making it invalid.
gboolean tracker_sparql_cursor_is_bound (TrackerSparqlCursor *cursor
,gint column
);
If the current row and column
are bound to a value, TRUE
is returned.
gboolean tracker_sparql_cursor_next (TrackerSparqlCursor *cursor
,GCancellable *cancellable
,GError **error
);
Iterates to the next result. This is completely synchronous and it may block.
void tracker_sparql_cursor_next_async (TrackerSparqlCursor *cursor
,GCancellable *cancellable
,GAsyncReadyCallback callback
,gpointer user_data
);
Iterates, asynchronously, to the next result.
gboolean tracker_sparql_cursor_next_finish (TrackerSparqlCursor *cursor
,GAsyncResult *res
,GError **error
);
Finishes the asynchronous iteration to the next result.
void
tracker_sparql_cursor_rewind (TrackerSparqlCursor *cursor
);
Resets the iterator to point back to the first result.
typedef struct _TrackerSparqlCursor TrackerSparqlCursor;
The TrackerSparqlCursor object represents an iterator of results.
Enumeration with the possible types of the cursor's cells
“connection”
property“connection” TrackerSparqlConnection *
The TrackerSparqlConnection used to retrieve the results.
