Cela correspond auxpì eces qui peuventêtrepeuventêtre déterminées au moment de la compilation, même si ce rapprochement des points de jonction se fait par interprétation lors de l'exécution, car l'instance de Joinpoint contient plusieursélémentsplusieurséléments d'information statique (accessible par getStaticPart()).
