For sole determination of allowed types for constraint annotations
you wouldn't need any validator implementations (or HV core) on the
AP classpath when working with the mirror API, just BV API and the
AP itself.
You do. Otherwise how do you make custom constraint work?
Actually not. From an element annotated with a constraint annotation
you can
- get the annotation mirrors
- filter on those annotated themselves with @Constraint
- retrieve the element value with name "validatedBy"
- retrieve the type mirrors contained
- retrieve the value of the 2nd type argument and check the type of
the annotated element against it
The classes referenced by the validatedBy *are* the validator classes
at least if by validator you mean ConstraintVaildator implementation
of the custom constraint, so they have to be in the classpath to be
mirrored by the AP machinery :)
For built-in types it's a bit different as the @Constraint is not
filled up and has to be simulated.
