Description [src]
abstract class Tracker.Batch : GObject.Object
{
/* No available fields */
}TrackerBatch executes a series of SPARQL updates and RDF data
insertions within a transaction.
A batch is created with tracker_sparql_connection_create_batch().
To add resources use tracker_batch_add_resource(),
tracker_batch_add_sparql() or tracker_batch_add_statement().
When a batch is ready for execution, use tracker_batch_execute()
or tracker_batch_execute_async(). The batch is executed as a single
transaction, it will succeed or fail entirely.
This object has a single use, after the batch is executed it can only be finished and freed.
The mapping of blank node labels is global in a TrackerBatch,
referencing the same blank node label in different operations in
a batch will resolve to the same resource.
