Interface Validator

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface Validator

A validator can be connected to a normal field declaration in OVL. The validator checks the validity of a value before it is assigned to the field. If the value is not valid the assignment is ignored. A class implementing this interface must contain a parameterless public constructor.
