Example 91 with DatasetGraph

use of org.apache.jena.sparql.core.DatasetGraph in project jena by apache.

the class AbstractTestTransSeq method trans_04.

@Test
public void trans_04() {
    // WRITE-abort-READ-check
    StoreConnection sConn = getStoreConnection();
    DatasetGraphTxn dsgW = sConn.begin(ReadWrite.WRITE);
    dsgW.add(q);
    assertTrue(dsgW.contains(q));
    dsgW.abort();
    dsgW.end();
    DatasetGraphTxn dsg2 = sConn.begin(ReadWrite.READ);
    assertFalse(dsg2.contains(q));
    dsg2.end();
    sConn.flush();
    DatasetGraph dsg = sConn.getBaseDataset();
    assertFalse(dsg.contains(q));
}

Example 92 with DatasetGraph

use of org.apache.jena.sparql.core.DatasetGraph in project jena by apache.

the class AbstractTestTransSeq method trans_readBlock_06.

@Test
public void trans_readBlock_06() {
    // WRITE(start)-READ(start)-WRITE(commit)-READ sees old DSG.
    // READ before WRITE remains seeing old view - READ after WRITE starts 
    StoreConnection sConn = getStoreConnection();
    DatasetGraphTxn dsgW = sConn.begin(ReadWrite.WRITE);
    DatasetGraphTxn dsgR = sConn.begin(ReadWrite.READ);
    dsgW.add(q);
    dsgW.commit();
    dsgW.end();
    assertFalse(dsgR.contains(q));
    dsgR.end();
    DatasetGraphTxn dsgR2 = sConn.begin(ReadWrite.READ);
    assertTrue(dsgR2.contains(q));
    dsgR2.end();
    sConn.flush();
    DatasetGraph dsg = sConn.getBaseDataset();
    assertTrue(dsg.contains(q));
}
