Hi, Java 8 introduced a new type Optional which may be used to represent objects which may be set or not set: private Optional<String> name; Hibernate Validator will allow to validate properties of this type in the next release. Now someone brought up the question whether the same is planned for ORM, so one can use Optional in entity properties. Any thoughts? Thanks, --Gunnar _______________________________________________ hibernate-dev mailing list hibernate-dev(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/hibernate-dev

I think it depends on the specific case how easy or hard this will be to achieve. If it's something rather isolated such as a specific user type it's easy, but in other cases it's more painful (e.g. marking annotation types as repeatable cannot really be done in a backwards-compatible manner, so it needs effectively two variants of such an annotation). --Sanne > > On 28 July 2014 07:36, Gunnar Morling <gunnar(a)hibernate.org&gt; wrote: > > Hi, > > > > Java 8 introduced a new type Optional which may be used to represent > > objects which may be set or not set: > > > > private Optional<String> name; > > > > Hibernate Validator will allow to validate properties of this type in the > > next release.
