reference to the host application in order to perform its work. This may not occur in the first versions of the plugin API but a resource needs to simply become the mapping mechanism by which parameters are taken from the REST side of the application and mapped into a method call within a given Plexus component. Whether that be the core Nexus application or a component provided by a plugin.

At the very least in the short term the resource needs to know how to look up the component that is required...

En déclarant les types de vos variables, cela permet aux différents outils comme les éditeurs de texte d'offrir un meilleur support.

Ce chapitre n'est qu'un **tutoriel rapide / rappel** sur les annotations de type Python.
