Examples with NodeIterator javax.jcr.NodeIterator used on opensource projects

Example 1 with NodeIterator

use of javax.jcr.NodeIterator in project jackrabbit by apache.

the class AutoFixCorruptNode method testAutoFix.

public void testAutoFix() throws Exception {
    // new repository
    TransientRepository rep = new TransientRepository(new File(TEST_DIR));
    Session s = openSession(rep, false);
    Node root = s.getRootNode();
    // add nodes /test and /test/missing
    Node test = root.addNode("test");
    Node missing = test.addNode("missing");
    missing.addMixin("mix:referenceable");
    UUID id = UUID.fromString(missing.getIdentifier());
    s.save();
    s.logout();
    destroyBundle(id, "workspaces/default");
    // login and try the operation
    s = openSession(rep, false);
    test = s.getRootNode().getNode("test");
    // try to add a node with the same name
    try {
        test.addNode("missing");
        s.save();
    } catch (RepositoryException e) {
    // expected
    }
    s.logout();
    s = openSession(rep, true);
    test = s.getRootNode().getNode("test");
    // iterate over all child nodes fixes the corruption
    NodeIterator it = test.getNodes();
    while (it.hasNext()) {
        it.nextNode();
    }
    // try to add a node with the same name
    test.addNode("missing");
    s.save();
    // try to delete the parent node
    test.remove();
    s.save();
    s.logout();
    rep.shutdown();
    FileUtils.deleteDirectory(new File("repository"));
}

/**
     * Checks if jcr:deref works when dereferencing into the version storage.
     */

    Node referenced = testRootNode.addNode(nodeName1);
    referenced.addMixin(mixVersionable);
    testRootNode.save();
    Version version = referenced.checkin();
    Node referencedVersionNode = version.getNode(jcrFrozenNode);
    Node referencer = testRootNode.addNode(nodeName2);
    referencer.setProperty(propertyName1, referencedVersionNode);
    testRootNode.save();
    String query = "/" + testRoot + "/*[@" + propertyName1 + "]/jcr:deref(@" + propertyName1 + ",'*')";
    QueryManager qm = superuser.getWorkspace().getQueryManager();
    Query q = qm.createQuery(query, Query.XPATH);
    QueryResult qr = q.execute();
    NodeIterator ni = qr.getNodes();
    assertEquals("Must find one result in query", 1, ni.getSize());
    while (ni.hasNext()) {
        Node node = (Node) ni.next();
        assertTrue(node.getProperty("jcr:frozenUuid").getString().equals(referenced.getUUID()));
    }

    assertEquals(2, nodes.getSize());
    if (result instanceof JackrabbitQueryResult) {
        assertEquals(3, ((JackrabbitQueryResult) result).getTotalSize());
    }
    // JCR-2684: offset higher than total result => size == 0
    query.setOffset(10);
    result = query.execute();
    nodes = result.getNodes();
    assertFalse(nodes.hasNext());
    assertEquals(0, nodes.getSize());
