[xwiki-devs] edit right and addobject

I use the addObject method to create new annotation, my plugin. When a user submit the form to add an annotation, i call addObject('annotationClass') . But, to invoke this method, user might have the edit right. And i'd like to have possibility to annotate with only comment right. How to create a method addAnnotation that need only comment right to be called? Thank for your time. Antoine
