Interface CriteriaBuilder


public interface CriteriaBuilder

Used to construct criteria queries, compound selections, expressions, predicates, orderings.

Note that Predicate is used instead of Expression<Boolean> in this API in order to work around the fact that Java generics are not compatible with varags.

Since:
Java Persistence 2.0
