Supporting the Integration and Evolution of Components Through Binary Component Adaptation
Ralph Keller and Urs Hölzle
Abstract:
Object-oriented components are hard to integrate if developed
independently of each other, and difficult to evolve without affecting
existing clients, particularly with widely distributed components that
have thousands of reusers. We propose binary component adaptation
(BCA), a new solution that allows components to be adapted and evolved
in binary form and on-the-fly (during program load ing). Binary
component adaptation rewrites component binaries before (or while)
they are loaded and is significantly more flexible than previous
approaches. Also, BCA requires no source code access and guarantees
release-to-release compatibility. That is, an adaptation is guaranteed
to be compatible with a new binary release of the component as long as
the new release itself is compatible with clients compiled using the
earlier release. We show how binary component adaptation can solve a
number of important integration and evolution problems and discuss how
it can be implemented for JVM class files (e.g., Java programs). We
believe that binary component adaptation could significantly improve
the integration and evolution of software components, especially in a
relatively uncoordinated and fast-evolving environment such as the
Internet.
