چکیده

A key technology to enable separation of concerns is the final step of reintegrating multiple, possibly independentlydeveloped modules. We argue for a technique of transformation, where the process of modifying a class to exhibit new behevior is controlled by a user-supplied program. Additionally, we argue that performing such a process as a program is loaded offers benefits in flexibility, performance, and reusability. We refer to this as load-time transformation. We describe the advantages of such a technique, present the implementation of our prototype, JOIE, and discuss our experience in developing a transformation that adds the capability of running consistent replicas over multiple machines.
