Hi, I'm quite late in the game but I finally had a chance to look at your main paper http://www.ii.uib.no/publikasjoner/texrap/pdf/2009-389.pdf
I quite like your approach for boolean composition. It is very elegant and can easily be added in a non breaking way to Hibernate Validator and Bean Validation. You guys are already prototyping it, so all good :) For cross-property validation, Hardy has reflected my position already. That being said, I wonder whether you can write your approach atop a generic class-level constraint @CrossValidation that would look for the properties annotations and behave as expected. That would be a nice way to offer both world to the users. You will need to "group" cross field constraints though: as I see it on the paper, you can only have one group of cross level constraint for a given constraint type per class. PS: I am not necessarily convinced by the all-but-one property is null use case though. I smells like a bad OO design in the first place that lead to such need. But I can be wrong :) Emmanuel On 22 sept. 2010, at 09:08, Federico Mancini wrote: > Hi all, > I am new to the list and I am opening this thread on Emmanuel Bernard's > suggestion, in order to > discuss some possible extensions to the validator (jsr 303) I have been > working on with a couple of collegues. > Mainly it concerns the possibility to extend composition with boolean > operators (ex.: A field is either in the range 1-10 OR 20-30 AND > notNull) and allow validation of sets of interdependent properties > (ex.: EITHER the name field is notNull OR the surname field is notNull/ > AT LEAST 1 field must be filled/etc....). > > A description of the experimental framework we implemented can be found > here http://www.ii.uib.no/publikasjoner/texrap/pdf/2009-389.pdf , and > some further discussion on the choices we made here > http://www.ii.uib.no/~federico/papers/Annotations.pdf. > > I hope this might be of some interest for the Hybernate Validator project, > but, even if not, it would be nice to get some feedback. > > Thanks, > Federico Mancini > _______________________________________________ > hibernate-dev mailing list > hibernate-dev@lists.jboss.org > https://lists.jboss.org/mailman/listinfo/hibernate-dev _______________________________________________ hibernate-dev mailing list hibernate-dev@lists.jboss.org https://lists.jboss.org/mailman/listinfo/hibernate-dev
