public class TypeConstraint
extends KeyedEnumerablePConstraint<IInputKey>
implements ITypeConstraint
Represents an enumerable type constraint that asserts that values substituted for the given tuple of variables
form a tuple that belongs to an enumerable extensional relation identified by an
IInputKey
.
The InputKey must be enumerable!
