Remarques

Pour obtenir l’objet Configuration d’une ressource, votre code doit disposer de privilèges de lecture sur tous les fichiers de configuration à partir desquels il hérite des paramètres. Pour mettre à jour un fichier de configuration, votre code doit également disposer de privilèges d’écriture pour le fichier de configuration et le répertoire dans lequel il existe.
