Example 54 with Predicate

use of com.hazelcast.query.Predicate in project hazelcast by hazelcast.

the class NotPredicateTest method negate_thenReturnInnerPredicate.

@Test
public void negate_thenReturnInnerPredicate() {
    Predicate inner = mock(Predicate.class);
    NotPredicate notPredicate = new NotPredicate(inner);
