Examples with Binding org.apache.jena.sparql.engine.binding.Binding used on opensource projects

Example 26 with Binding

use of org.apache.jena.sparql.engine.binding.Binding in project jena by apache.

the class TestExpressions3 method binding.

private static Binding binding(String bindingStr) {
    if (bindingStr == null || bindingStr.matches("\\s*\\(\\s*\\)\\s*"))
        return null;
    Item item = SSE.parse("(binding " + bindingStr + ")");
    Binding binding = BuilderBinding.build(item);
    return binding;
}

Example 27 with Binding

use of org.apache.jena.sparql.engine.binding.Binding in project jena by apache.

the class TestExpressions3 method eval.

// From SPARQL syntax
private static void eval(String string, String bindingStr, boolean expected) {
    Binding binding = binding(bindingStr);
    Expr expr = ExprUtils.parse(string);
    NodeValue nv = expr.eval(binding, FunctionEnvBase.createTest());
    boolean b = XSDFuncOp.booleanEffectiveValue(nv);
    assertEquals(string, expected, b);
}

Example 28 with Binding

use of org.apache.jena.sparql.engine.binding.Binding in project jena by apache.

the class AbstractTestDistinctReduced method distinct.

private void distinct(List<String> data, List<String> results) {
    // Distinct Iterators are not required to preserve order.
    List<Binding> input = build(data);
    List<Binding> output = build(results);
    QueryIterator qIter = createQueryIter(input);
    List<Binding> iterList = Iter.toList(qIter);
    assertEquals(output + " :: " + iterList, output.size(), iterList.size());
    // Assume results has no duplicates so same size, same members => order dependent same.
    Set<Binding> testExpected = new HashSet<>(output);
    Set<Binding> testResult = new HashSet<>(iterList);
    assertEquals(testExpected, testResult);
}

Example 29 with Binding

use of org.apache.jena.sparql.engine.binding.Binding in project jena by apache.

@Test
public void testCloseWhenBagPresent() {
    params.set(ARQ.spillToDiskThreshold, 0);
    QueryIteratorBase base = new MockQueryIterator(BindingFactory.create());
    QueryIterDistinct d = new QueryIterDistinct(base, c);
    assertNull(d.db);
    Binding ignored = d.next();
    assertNotNull(d.db);
    DistinctDataBag<Binding> bag = d.db;
    d.close();
    assertTrue(bag.isClosed());
    assertNull(d.db);
}
