yes, you could write a validator as such:


namespace F3\MyPackage\Domain\Validator;
use F3\MyPackage\Domain\Model\Event;

class EventValidator implements \F3\FLOW3\Validation\Validator\ValidatorInterface {

	public function isValid($value) {
		if (!$value instanceof Event) {
			return FALSE;
		}
		return ($value->getBegin() >= $value->getEnd());
	}

	...
}

yes

In that case you can use Reflection, but I don't recommend that – it's better
to provide a getter for it. If you still want to use Reflection, there will
be a special support for it in the ObjectAccess class in FLOW3 1.0 beta 1.
But you can of course just use ReflectionProperty for it.

Cheers,
Robert
