class GenericProjectInfo(project_id: str, project_keystone_api_version: str, domain_id: Optional[str] = None, name: Optional[str] = None, description: Optional[str] = None)¶

Bases: object

validate_project_and_authorize(context: context.RequestContext, project_id: str, policy_check: str, validate_only: bool = False) → None¶

walk_class_hierarchy(clazz: type, encountered: Optional[list[type]] = None) → Generator[type, None, None]¶

Walk class hierarchy, yielding most derived classes first.
