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. )idT)create force_uniqueN) algorithm)super__init__flagsdnsopcodeto_flagsr isinstancestrname from_textorigin rdataclass RdataClassmake zone_rdclass find_rrsetzone rdatatypeSOAuse_tsig)selfr*rdclasskeyringkeyname keyalgorithmr __class__rr r.s  zUpdateMessage.__init__cC |jdS)zThe zone section.rsectionsr.rrr r*M zUpdateMessage.zonecC||jd<dS)Nrr6r.vrrr r*RcCr5)zThe prerequisite section.rr6r8rrr prerequisiteVr9zUpdateMessage.prerequisitecCr:)Nrr6r;rrr r>[r=cCr5)zThe update section.rr6r8rrr update_r9zUpdateMessage.updatecCr:)Nrr6r;rrr r?dr=c CsB|dur|j}|}||||j|j||dd}|||dS)z&Add a single RR to the update section.NT)r?coversr)r(rdtypeadd)r.r"ttlrddeletingsectionr@rrsetrrr _add_rrhszUpdateMessage._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.
