libhibernate-validator4-java - 4.3.4-4 main

Hibernate Validator aims at defining and checking a domain model
level constraints. It supports custom constraints definitions as well
as full internationalization. Annotations are used to define
constraints on object level. The validation mechanism can be executed
in different layers in your application without having to duplicate
any of these rules (presentation layer, data access layer, Database
schema).
.
Hibernate Validator integrates with Hibernate by applying the
constraints on the database schema (DDL generation) and by checking
entity validity before Hibernate inserts or updates instances. You
can use Hibernate Validator with any Java Persistence provider, not
only Hibernate, although you will not be able to use automatic DDL
alteration for constraint generation outside of Hibernate
EntityManager.
