Several authors have identified that the only feasible way to increase productivity in software construction is to reuse existing software. To achieve this, component-based software development is one of the more promising approaches. However, traditional research in component-oriented programming often assumes that components are reused "as-is". Practitioners have found that "as-is" reuse seldomly occurs and that reusable components generally need to be adapted to match the system requirements. Existing component object models provide only limited sup-port for component adaptation, i.e. white-box techniques such as copy-paste and inheritance and black-box approaches such as aggregation and wrapping. These techniques suffer from problems related to reusability, effi-ciency, implementation overhead or the self problem. To address these problems, this paper proposes superimposi-tion, a novel black-box adaptation technique that allows one to impose predefined, but configurable types of functionality on a reusable component. Three categories of typical adaptation types are discussed, related to the component interface, component composition and component monitoring. Superimposition and the types of com-ponent adaptation are exemplified by several examples.
