Is there a way to pass a jpa predicate array to the criteriabuilder IN KOTLIN?

Question

The solution proposed in: https://stackoverflow.com/a/11138229/1270045 works pretty fine in java but i am in kotlin. How can that be done here that i pass a predicate array to the criteria builder written in kotlin?

So its about writing this in kotlin that i can be passed on:

cq.select(customer).where(predicates.toArray(new Predicate[]{}));

My example code:

val predicates = mutableListOf<Predicate>()
if (XYZ != null) {
    val XYZPath = element.get<Long>("XYZ")
    predicates.add(criteriaBuilder.equal(XYZPath, XYZ))
}
criteriaQuery.select(element)
    .where(criteriaBuilder.or(???))

Is it the `predicates.toArray(new Predicate[predicates.size()])` part you have trouble with? — marstran, Jan 23 '19 at 11:22
Yes and i tried that but a java array is expected as the java method is defined by `Predicate ...` as parameter — rom, Jan 23 '19 at 11:30

Thanks to marstran for your help that solved it:

criteriaQuery.select(element)
    .where(criteriaBuilder.or(*predicates.toTypedArray()))
