Class DatasetGraphTransaction

java.lang.Object
org.apache.jena.sparql.core.DatasetGraphWrapper
org.apache.jena.tdb1.transaction.DatasetGraphTransaction
All Implemented Interfaces:

public class DatasetGraphTransaction extends org.apache.jena.sparql.core.DatasetGraphWrapper implements org.apache.jena.atlas.lib.Sync
A transactional DatasetGraph that allows one active transaction per thread. DatasetGraphTxn holds the Transaction object. This is analogous to a "connection" in JDBC. Not considered to be in the public API.
