Chapter

Abstract

In this chapter, concepts already addressed in previous chapters are reconsidered and extended to cater for modularity. In particular, it is shown how method contracts can be used in proofs (as opposed to being verified themselves). Another central topic is nonfunctional framing information, i.e., information on what locations a method may write to or read from. But, there are also items that are discussed here in depth for the first time: model methods, an abstraction of Java methods that are only used in specification, verification of recursive methods, and object invariants. For any of the arising proof obligations the calculus rules needed to dispatch them are shown.
