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)ZcreateZ force_uniqueN) algorithm)super__init__flagsdnsZopcodeZto_flagsr isinstancestrname from_textorigin rdataclass RdataClassmake zone_rdclass find_rrsetr rdatatypeSOAZuse_tsig)selfrrrrrr __class__r r r 1s$  zUpdateMessage.__init__)returncCs |jdS)zThe zone section.rZsectionsr/r r r r\szUpdateMessage.zonecCs||jd<dS)Nrr3r/vr r r rascCs |jdS)zThe prerequisite section.rr3r4r r r prerequisiteeszUpdateMessage.prerequisitecCs||jd<dS)Nrr3r5r r r r7jscCs |jdS)zThe update section.rr3r4r r r updatenszUpdateMessage.updatecCs||jd<dS)Nrr3r5r r r r8ssc CsB|dur|j}|}||||j|j||dd}|||dS)z&Add a single RR to the update section.NT)r8coversr,r+rdtypeadd)r/r%ttlrddeletingsectionr9rrsetr r r _add_rrwszUpdateMessage._add_rrc Gst|trtj|d}t|dtjjrf|D]4}|rD|||j|D]}|j ||j ||dqHq.nt |}t | d}t|dtjjr|r|||dj|D]}|j ||||dqnVtjj| d}|r||||D],} tj|j|| |j}|j ||||dqdS)aAdd records. *replace* is the replacement mode.
