                                                                         boolean filter)
        Get entity-filtering scopes from given annotations. Scopes are only derived from entity-filtering annotations.
        Parameters:
        annotations - list of arbitrary annotations.
        filter - true whether the given annotation should be reduced to only entity-filtering annotations, false otherwise.
        Returns:
        a set of entity-filtering scopes.
      • getFilteringAnnotations

        public static java.lang.annotation.Annotation[] getFilteringAnnotations​(java.lang.annotation.Annotation[] annotations)
