public interface AssignmentConstraintContext<V extends Variable<V,T>,T extends Value<V,T>>
extends AssignmentContext

An extension of the simple AssignmentContext which is used by the ConstraintWithContext class. The notification methods assigned and unassigned are automatically called by the constraint whenever a variable of the constraint is assigned or unassigned respectively.
