A case study in re-engineering to enforce architectural control flow and data sharing

Without rigorous software development and maintenance, software tends to lose its original architectural structure and become difficult to understand and modify. ArchJava, a recently proposed programming language which embeds a componentand-connector architectural specification within Java implementation code, offers the promise of preventing the loss of architectural structure. AliasJava, which can be used in conjunction with ArchJava, is an annotation system that extends Java to express how data is confined within, passed among, or shared between components and objects in a software system. We describe a case study in which we incrementally re-engineer an existing Java implementation to obtain an implementation which enforces the architectural control flow and data sharing. Building on results from similar case studies, we chose an application consisting of over 16,000 source lines of Java code and over 90 classes. We describe our process, the detailed steps involved (some of wh...
