Re: [bv-dev] Dependency between constraints and validators
Ah, I wasn't aware that you had annotation processing in mind.
What I was thinking about was how to make addBinding() type safe in
that way that one can't pass a validator type not appropriate for the
constraint type, which would work using the right type parameters.

Imagine the following code
void main(args[] args) {
ValidatorFactory factory = Validation
.byDefaultProvider()
.configure()
.addBinding(NotNull.class, NumberNotNullValidator.class)
.createValidatorFactory();
public static class Address {
@NotNull String getStreet() { ... };
}
}
How would an annotation processor know that the factory is configured to bind NotNull
with NumberNotNullValidator and thus that Address.getStreet cannot be validated?
