Analysing the Java package/access concepts in Isabelle/HOL
Norbert W. Schirmer · Concurrency and Computation Practice and Experience · 2004
Abstract Java access modifiers and packages provide a mechanism to restrict access to members and types, as an additional means of information hiding beyond the purely object‐oriented concept of classes. In this paper we clarify the semantics of access modifiers and packages by adding them to our formal model of Java in the theorem prover Isabelle/HOL. We analyse which properties we can rely on at runtime, provided that the program has passed the static accessibility tests. Copyright © 2004 John Wiley & Sons, Ltd.
