On Dynamic Reconfiguration of Behavioural Adaptations
نویسندگان
چکیده
Software components are now widely used in the development of systems. However, incompatibilities between their observable interfaces may happen and then make their composition impossible. Software adaptation aims at generating as automatically as possible new components called adaptors whose role is to compensate such incompatibilities. Since development of adaptors is costly, it is crucial to make their reconfiguration possible when one wants to modify or update some parts of a running system involving adaptors. In this first attempt, we present the problem of dynamically reconfiguring adaptors and we sketch some ideas of solution on an example. Finally, we end with a list of open issues to be worked out.
