Abstract:

Component-orientation is an emerging paradigm that promises components that are usable as prefabricated black-boxes. But components have the problem that they should be exchangeable and flexibly adaptable to a huge number of different application contexts and to changing requirements. We will argue, that sole parameterization -- as the key variation technique of components -- is not suitable to cope with all required change scenarios. A proper integration with multiple other paradigms, such as object-orientation, the usage of a scripting language as a flexible component glue, and the exploitation of high-level interception techniques can make components be easier (ex)-changeable and adaptable. These techniques can be applied without interfering with the component's internals.
