Example 11 with Attribute

use of javax.persistence.metamodel.Attribute in project jbpm by kiegroup.

the class QueryCriteriaUtil method createPredicateFromSingleCriteria.

 *
 * @param query The {@link CriteriaQuery} that is being built
 * @param criteria The given {@link QueryCriteria} instance

 * @param queryType The (persistent {@link Entity}) {@link Class} that we are querying on
 * @return A {@link Predicate} created on the basis of the given {@link QueryCriteria}
