See the documentation of the Message class for a complete description of the keyring dictionary. *zone*, a ``dns.name.Name``, ``str``, or ``None``, the zone which is being updated. ``None`` should only be used by dnspython's message constructors, as a zone is required for the convenience methods like ``add()``, ``replace()``, etc. *rdclass*, an ``int`` or ``str``, the class of the zone. The *keyring*, *keyname*, and *keyalgorithm* parameters are passed to ``use_tsig()``; see its documentation for details. )r"T)create force_uniqueN) algorithm)super__init__flagsdnsopcodeto_flagsr isinstancestrname from_textorigin rdataclass RdataClassmake zone_rdclass find_rrsetr rdatatypeSOAuse_tsig)selfrrrr r!r" __class__s rr(zUpdateMessage.__init__1s0 B cj))#**;<<< dC  ,8%%d++D .+0099# ;  OO   !!
