Example 1 with PropertySequence

use of org.apache.jackrabbit.commons.flat.PropertySequence in project jackrabbit by apache.

the class ItemSequenceTest method testSingletonPropertySequence.

    Comparator<String> order = Rank.<String>comparableComparator();
    TreeManager treeManager = new BTreeManager(testNode, 2, 4, order, true);
    PropertySequence properties = ItemSequence.createPropertySequence(treeManager, errorHandler);
    ValueFactory vFactory = testNode.getSession().getValueFactory();
    properties.addProperty("key", vFactory.createValue("key_"));
    assertTrue(properties.hasItem("key"));
    Iterator<Property> propertyIt = properties.iterator();
    assertTrue(propertyIt.hasNext());
