Support linguistique à la constitution de bibliothèques de méta-composants

Although reflexion is promising as a candidate to solve a large set of problems, its use is not as widely spread as it could be expected. We believe this is due to the increase of complexity it introduces. To ease the use of reflexion, we propose to build some set of libraries of reflective programs. Unfortunately, actor languagesdo not hold the required tools to build them. That is why we introduced the linguistic support required to build such libraries. Our proposal is based on a specification of the causal link. Each behavior of a meta-component, an actor which is a part of the meta of an actor, includes such a specification. With this modification of the causal link’s sight, this specification introduces a clear separation between differents levels of uses and releases the end-user from the duty to perfectly know the meta-protocol. MOTS-CLÉS : acteurs, réflexivité, bibliothèques de méta-composants.
