Example 24 with Predicate

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

the class MapPredicateTest method predicateBuilder.

@TimeStep(prob = 0.2)
public void predicateBuilder(ThreadState state) {
    long startMs = System.currentTimeMillis();
    int age = state.randomInt(Employee.MAX_AGE);
    String name = Employee.getRandomName();
    // TODO: Still broken because it relies on reflection which is dog slow, so we need an explicit AgeNamePredicate
    EntryObject entryObject = new PredicateBuilder().getEntryObject();
    Predicate agePredicate = entryObject.get("age").lessThan(age);
    Predicate ageNamePredicate = entryObject.get("name").equal(name).and(agePredicate);
