Examples with Transactional org.apache.jena.dboe.transaction.Transactional used on opensource projects

Example 1 with Transactional

use of org.apache.jena.dboe.transaction.Transactional in project jena by apache.

the class TestBPlusTreeTxn method bptree_txn_05.

// Two transactions, second an insert no-op.
// Relies on all blocks not being full and so not being
// split on the way down due to the early split algorithm.
@Test
public void bptree_txn_05() {
    BPlusTree bpt = createBPTree();
    int outerRootIdx1 = bpt.getRootId();
    Transactional thing = transactional(bpt);
    Txn.executeWrite(thing, () -> {
        IndexTestLib.add(bpt, 1, 2, 3);
    });
    int outerRootIdx2 = bpt.getRootId();
    assertNotEquals("After txn(1)", outerRootIdx1, outerRootIdx2);
    Txn.executeWrite(thing, () -> {
        IndexTestLib.add(bpt, 1, 2);
    });
    int outerRootIdx3 = bpt.getRootId();
    assertNotEquals("After txn (2)", outerRootIdx1, outerRootIdx3);
    assertEquals("After txn (3)", outerRootIdx2, outerRootIdx3);
}

Example 3 with Transactional

use of org.apache.jena.dboe.transaction.Transactional in project jena by apache.

the class TestBPlusTreeTxn method bptree_txn_02.

// Commit - only the first changes the root.
@Test
