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. )rT)create force_uniqueN) algorithm)super__init__flagsdnsopcodeto_flagsr isinstancestrname from_textorigin rdataclass RdataClassmake zone_rdclass find_rrsetr rdatatypeSOAuse_tsig)selfrrrrrr __class__r r r"4s&  zUpdateMessage.__init__returncC |jdS)zThe zone section.rsectionsr4r r r r_ zUpdateMessage.zonecC||jd<dS)Nrr9r4vr r r rdcCr8)zThe prerequisite section.rr9r;r r r prerequisitehr<zUpdateMessage.prerequisitecCr=)Nrr9r>r r r rAmr@cCr8)zThe update section.rr9r;r r r updateqr<zUpdateMessage.updatecCr=)Nrr9r>r r r rBvr@c CsB|dur|j}|}||||j|j||dd}|||dS)z&Add a single RR to the update section.NT)rBcoversr0r/rdtypeadd)r4r)ttlrddeletingsectionrCrrsetr r r _add_rrzszUpdateMessage._add_rrc Gs t|tr tj|d}t|dtjjr4|D]}|r"|||j|D] }|j ||j ||dq$qdSt |}t | d}t|dtjjrc|rS|||dj|D] }|j ||||dqUdStjj| d}|ru||||D]} tj|j|| |j}|j ||||dqwdS)aAdd records. *replace* is the replacement mode.
