public class DatasetGraphWithLock
extends DatasetGraphTrackActive
implements Sync

A DatasetGraph that uses the dataset lock to give weak transactional behaviour, that is the application see transaction but they are not durable. Only provides multiple-reader OR single-writer, and no write-transction abort.
