Migrating Large Object-oriented Applications into Component-based ones: Instantiation and Inheritance Transformation
Large object-oriented applications have complex and numerous dependencies, and usually do not have explicit architectures. Therefore they are hard to maintain, and parts of them are difficult to reuse. Component-based development paradigm emerged for improving these aspects and for supporting effective maintainability and reuse. It provides better understandability through a high-level architecture view. Thereby migrating object-oriented applications to component-based ones will contribute to improve these characteristics. In this paper, we propose an approach to automatically transform object-oriented applications to component-based ones. More particularly, the input of the approach is the result provided by software architecture recovery: a component-based architecture description. Then, our approach transforms the object-oriented source code in order to produce deployable components. We focus in this paper on the transformation of source code related to instantiation and inheritance dependencies between classes that are in different components. We experimented the proposed solution in the transformation of a collection of Java applications into the OSGi framework. The experimental results are discussed in this paper.
