Re: [bv-dev] Bean Validation and lambda expressions

Hi, I'm not sure what's the current state regarding method references in Java 8. If they're in, we might make use of them for property validation: validator.validateProperty(car, Car::getManufacturer); validator.validateValue(Car::manufacturer, "Morris"); Or if we add one day an API for programmatic constraint definition (example based on the API in HV): ConstraintMapping mapping = new ConstraintMapping(); mapping.type( Car.class ) .property( Car::getManufacturer" ) .constraint( NotNull.class ) .constraint( Size.class ).with( Size::min, 2).with( Size::max, 14 ); That's just a quick thought, not sure whether that really works or makes too much sense, though. --Gunnar 2012/10/8 Matt Benson <mbenson(a)apache.org&gt;: > That was my reaction as well, wondering whether anyone else would > propose any ways of augmenting the BV APIs to include > lambda-compatible interfaces. > > Matt > > On Mon, Oct 8, 2012 at 11:07 AM, Michael Nascimento <misterm(a)gmail.com&gt; wrote: >> Given there are no function types for now, I wonder what sort of >> impact could it have... >> >> Regards, >> Michael >> >> On Mon, Oct 8, 2012 at 8:59 AM, Emmanuel Bernard < emmanuel(a)hibernate.org&gt; wrote: >>> How do you think Java 8 lambda expression support will affect Bean >>> Validation APIs?
