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)createZ force_uniqueN) algorithm)super__init__flagsdnsopcodeZto_flagsr isinstancestrname from_textorigin rdataclass RdataClassmake zone_rdclass find_rrsetr rdatatypeSOAZuse_tsig)selfrrrrrr __class__r r r#1s&  zUpdateMessage.__init__returncC |jdS)zThe zone section.rsectionsr3r r r r\ zUpdateMessage.zonecC||jd<dS)Nrr8r3vr r r racCr7)zThe prerequisite section.rr8r:r r r prerequisiteer;zUpdateMessage.prerequisitecCr<)Nrr8r=r r r r@jr?cCr7)zThe update section.rr8r:r r r updatenr;zUpdateMessage.updatecCr<)Nrr8r=r r r rAsr?c CsB|dur|j}|}||||j|j||dd}|||dS)z&Add a single RR to the update section.NT)rAcoversr0r/rdtypeadd)r3r)ttlrddeletingsectionrBrrsetr r r _add_rrwszUpdateMessage._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.
