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.

That was my reaction as well, wondering whether anyone else would
propose any ways of augmenting the BV APIs to include
lambda-compatible interfaces.
