Examples with Transaction org.apache.jena.tdb.transaction.Transaction used on opensource projects

Example 1 with Transaction

use of org.apache.jena.tdb.transaction.Transaction in project jena by apache.

the class AbstractTestNodeTableTrans method nodetrans_06.

@Test

    NodeTableTrans ntt1 = create(txn1, node1);
    NodeId nodeId1 = ntt1.getBaseNodeTable().getNodeIdForNode(node1);
    ntt1.begin(txn1);
    NodeId nodeId2 = ntt1.getAllocateNodeId(node2);
    ntt1.commitPrepare(txn1);
    // READ - don't enact
    Transaction txn2 = createTxn(12);
    NodeTableTrans ntt2 = create(txn2, ntt1.getBaseNodeTable());
