public class GraphTxnTDB
extends GraphTDB
implements org.apache.jena.atlas.lib.Closeable, org.apache.jena.atlas.lib.Sync

Transaction-capable version of GraphTDB. Valid across transactions except where noted (caution: prefix mappings are not). Valid to use when TDB is not transactional.

GraphTxnTDB

public GraphTxnTDB(DatasetGraphTransaction dataset,
 org.apache.jena.graph.Node graphName)

Method Details

getDatasetGraphTransaction

public DatasetGraphTransaction getDatasetGraphTransaction()

Description copied from class: GraphTDB

Return the DatasetGraphTransaction. If this wrapping a base DatasetGraphTDB, return null.

Specified by:

getDatasetGraphTransaction in class GraphTDB

getDatasetGraphTDB

public DatasetGraphTDB getDatasetGraphTDB()

Description copied from class: GraphTDB

Return the associated DatasetGraphTDB. For non-transactional, that's the base storage. For transactional, it is the current transaction wrapper DatasetGraphTDB.

Immediate validity only. Not valid across transaction boundaries, nor non-transactional to transactional.

Specified by:

getDatasetGraphTDB in class GraphTDB
