public interface Restrictable

The Restrictable interface defines a standard set of methods for a class that wants to control its principle value by a Constraint. Since several constraints can be combined with logical operators, it doesn't make much sense to have more than one Constraint per value. It is better to use the appropriate logical-and respectively logical-or operators that fit best to the desired Constraint expression. The interface provides a standard for classes that want to use a Constraint, but this is not important to the general concept of a Constraint, which can be used in meaningful ways above and beyond the Restrictable interface.
