Dnspython modules may also define their own exceptions, which will always be subclasses of ``DNSException``. � )�Optional�Setc � � � e Zd ZU dZdZee ed< e� Z e e ed< dZ ee ed< � fd�Z d� Z d� Zd � Z� fd �Z� xZS ) � DNSExceptiona� Abstract base class shared by all dnspython exceptions. It supports two basic modes of operation: a) Old/compatible mode is used if ``__init__`` was called with empty *kwargs*. In compatible mode all *args* are passed to the standard Python Exception class as before and all *args* are printed by the standard ``__str__`` implementation. Class variable ``msg`` (or doc string if ``msg`` is ``None``) is returned from ``str()`` if *args* is empty. b) New/parametrized mode is used if ``__init__`` was called with non-empty *kwargs*. In the new mode *args* must be empty and all kwargs must match those set in class variable ``supp_kwargs``. All kwargs are stored inside ``self.kwargs`` and used in a new ``__str__`` implementation to construct a formatted message based on the ``fmt`` class variable, a ``string``. In the simplest case it is enough to override the ``supp_kwargs`` and ``fmt`` class variables to get nice parametrized messages.
