Examples of com.hp.hpl.jena.tdb.store.DatasetGraphTDB

com.hp.hpl.jena.tdb.store.DatasetGraphTDB
This is the class that creates a dataset over the storage via TripleTable, QuadTable and prefixes. These may be transactional. See also:
- {@link DatasetGraphTxn} – the sublcass that provides a single tranasaction
- {@link DatasetGraphTransaction} – class that provides the application with the right DatasetGraphTDB (base or transaction).
