public interface PredicateGenerator.CriterionHandlerProvider

SPI for contributing a CriterionHandler via java.util.ServiceLoader.

Create an implementation and register it in META-INF/services/org.grails.orm.hibernate.query.PredicateGenerator$CriterionHandlerProvider so that it is discovered automatically on first query execution — no BootStrap registration needed.

     // Example implementation (Groovy)
     class MyHandlerProvider implements PredicateGenerator.CriterionHandlerProvider {
         Class<? extends Query.Criterion> criterionType() { MyCriterion }
         PredicateGenerator.CriterionHandler criterionHandler() {
             { query, root, cb, criterion -> ... } as PredicateGenerator.CriterionHandler
         }
     }
