We present a way of de ning the subtype relation that ensures that subtype objects preserve behavioral properties of their supertypes. The subtype relation is based on the speci cations of the suband supertypes. Our approach handles mutable types and allows subtypes to have more methods than their supertypes. Dealing with mutable types and subtypes that extend their supertypes has surprising consequences on how to specify and reason about objects. In our approach, we discard the standard data… CONTINUE READING
