use of com.hazelcast.query.impl.predicates.RuleBasedQueryOptimizer in project hazelcast by hazelcast.

the class PagingPredicateOptimizationTest method testInnerPredicateOptimization.

@Test

    RuleBasedQueryOptimizer optimizer = new RuleBasedQueryOptimizer();
    Indexes indexes = mock(Indexes.class);
    Predicate[] orPredicates = new Predicate[10];
    for (int i = 0; i < orPredicates.length; ++i) {
        orPredicates[i] = Predicates.equal("a", i);
    }
    Predicate innerPredicate = Predicates.or(orPredicates);
    PagingPredicate<Object, Object> pagingPredicate = Predicates.pagingPredicate(innerPredicate, 10);
    Predicate optimized = optimizer.optimize(pagingPredicate, indexes);
    assertInstanceOf(PagingPredicateImpl.class, optimized);
    Predicate innerOptimized = ((PagingPredicateImpl) optimized).getPredicate();
    assertInstanceOf(InPredicate.class, innerOptimized);
