RRset inherits from Rdataset, and RRsets can be treated as Rdatasets in most cases. There are, however, a few notable exceptions. RRsets have different to_wire() and to_text() method arguments, reflecting the fact that RRsets always have an owner name. namedeletingNcs$tt|j|||||_||_dS)zCreate a new RRset.N)superr__init__rr)selfrrdclassrdtypecoversr) __class__/usr/lib/python3.6/rrset.pyr'szRRset.__init__cs"tt|j}|j|_|j|_|S)N)rr_clonerr)r obj)r rrr/sz RRset._clonecCs|jdkrd}ndtjj|jd}|jdk rDdtjj|j}nd}dt|jdtjj|jdtjj|j ||dS) Nr()z delete=z) r dns rdatatypeto_textr rdataclassstrrr r )r ZctextZdtextrrr__repr__5s  zRRset.__repr__cCs|jS)N)r)r rrr__str__Bsz RRset.__str__cs.t|tsdS|j|jkrdStt|j|S)zcTwo RRsets are equal if they have the same name and the same rdataset @rtype: boolF) isinstancerrr__eq__)r other)r rrrEs   z RRset.__eq__cs4tt|j|||sdS|j|ks,|j|kr0dSdS)zaReturns True if this rrset matches the specified class, type, covers, and deletion state.FT)rrmatchrr)r rr r r r)r rrr Ps z RRset.matchTc stt|j|j|||jf|S)aConvert the RRset into DNS master file format. @see: L{dns.name.Name.choose_relativity} for more information on how I{origin} and I{relativize} determine the way names are emitted.
