示例1: evaluate

import org.apache.marmotta.ldpath.model.selectors.PropertySelector; //导入依赖的package包/类
@Override
public Var evaluate(NodeSelector nodeSelector, ElementGroup elementGroup, Var var, LDPathEvaluatorConfiguration evaluatorConfiguration) {
    TestingSelector testingSelector = (TestingSelector) nodeSelector;
    FunctionTest functionTest = (FunctionTest) testingSelector.getTest();

    if(functionTest.getArgSelectors().get(0) instanceof PropertySelector) {
        PropertySelector arg = (PropertySelector) functionTest.getArgSelectors().get(0);
        PropertySelector delegate = (PropertySelector) testingSelector.getDelegate();

        Var target = Var.alloc(VarIDGenerator.createID());
        elementGroup.addTriplePattern(new Triple(var.asNode(), NodeFactory.createURI(delegate.getProperty().toString()), target));

        Var selector = Var.alloc(VarIDGenerator.createID());
        elementGroup.addTriplePattern(new Triple(target.asNode(), NodeFactory.createURI(arg.getProperty().toString()), selector.asNode()));

        elementGroup.addElementFilter(new ElementFilter(new E_IsLiteral(new ExprVar(selector))));

        return selector;
    } else {
        throw new IllegalStateException("Argument of function isLiteral has to be a PropertySelector");
    }
