The C-SAW and GenAWeave tools support evolution of legacy software through a two-level approach using aspects. The principle strategy of these tools is to generate low-level transformation rules from higher-level domain languages. The demonstration will show the ability to make rapid adaptations to a large cross- section of an application through simple specification changes at a high-level of abstraction. As case studies, the demonstration will highlight the transformation of two legacy commercial applications: a large mission-computing avionics framework written in C++, and a client-server enterprise management system implemented in Object Pascal. In the avionics application, transformation rules are generated from domain-specific models created in the Generic Modeling Environment (from Vanderbilt University). Using C-SAW, it will be shown that small changes in a representative model can regulate concurrency and logging policies across many C++ classes. The Object Pascal portion of the demonstration will illustrate the use of a program transformation system (the Design Maintenance System) as the underlying engine for an aspect weaver. A unique feature of the demonstration is the ability to weave aspects into various legacy languages (not just Java) at the source level using GenAWeave.
