Interface BaseEntityService.CriteriaQueryBuilder<E>

Type Parameters:

E - The generic base entity type.

Enclosing class:

BaseEntityService<I extends Comparable<I> & Serializable,E extends BaseEntity<I>>

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
protected static interface BaseEntityService.CriteriaQueryBuilder<E>

Functional interface to fine-grain a JPA criteria query for any of BaseEntityService.list(CriteriaQueryBuilder, Consumer) or BaseEntityService.find(CriteriaQueryBuilder, Consumer) methods.

You do not need this interface directly. Just supply a lambda. Below is an usage example:

 @Stateless
 public class YourEntityService extends BaseEntityService<YourEntity> {

     public List<YourEntity> getFooByType(Type type) {
         return list((criteriaBuilder, query, root) -> {
             query.where(criteriaBuilder.equal(root.get("type"), type));
         }, noop());
     }

 }
