Example 6 with NodeValueString

use of org.apache.jena.sparql.expr.nodevalue.NodeValueString in project jena by apache.

the class ExprFactoryTest method asListTest.

@Test
public void asListTest() {
    ExprList lst = factory.asList("?foo", "http://example.com", Converters.quoted("hello"), 1, 5L, 3.14f, 6.28d, Var.alloc("bar"), null, factory.rand());
    assertEquals(10, lst.size());
    assertEquals(new ExprVar("foo"), lst.get(0));
    // assertEquals( new ExprVar( "foo" ), lst.get(0));
    assertEquals(new NodeValueString("hello"), lst.get(2));
    assertEquals(1, lst.get(3).getConstant().asNode().getLiteralValue());
    assertEquals(5, lst.get(4).getConstant().asNode().getLiteralValue());
    assertEquals(3.14f, lst.get(5).getConstant().asNode().getLiteralValue());
    assertEquals(6.28, lst.get(6).getConstant().asNode().getLiteralValue());
    assertEquals(new ExprVar("bar"), lst.get(7));
    assertEquals(Expr.NONE, lst.get(8));
    assertEquals(new E_Random(), lst.get(9));

Example 7 with NodeValueString

use of org.apache.jena.sparql.expr.nodevalue.NodeValueString in project webofneeds by researchstudio-sat.

the class SparqlMatcherUtils method createSearchQuery.

public static Op createSearchQuery(String searchString, Var resultName, int hops, boolean disjunctive, boolean tokenize) {
    Var textSearchTarget = Var.alloc("textSearchTarget");
    Optional<Op> union = IntStream.range(1, hops + 1).mapToObj(hopCount -> makePathBGPPattern(resultName, textSearchTarget, hopCount, op -> {
        Expr filterExpression = Arrays.stream(tokenize ? searchString.toLowerCase().split(" ") : new String[] { searchString.toLowerCase() }).<Expr>map(searchPart -> new E_StrContains(new E_StrLowerCase(new ExprVar(textSearchTarget)), new NodeValueString(searchPart))).reduce((left, right) -> disjunctive ? new E_LogicalOr(left, right) : new E_LogicalAnd(left, right)).orElse(new NodeValueBoolean(true));
        return OpFilter.filterBy(new ExprList(filterExpression), op);
    })).reduce((op1, op2) -> new OpUnion(op1, op2));
    Op maintriple = new OpTriple(new Triple(resultName, RDF.type.asNode(), WON.Atom.asNode()));
    Op mainOp = union.isPresent() ? OpJoin.create(maintriple, union.get()) : maintriple;
