A node is either a CNAME node or an "other data" node. A CNAME node contains only CNAME, KEY, NSEC, and NSEC3 rdatasets along with their covering RRSIG rdatasets. An "other data" node contains any rdataset other than a CNAME or RRSIG(CNAME) rdataset. When changes are made to a node, the CNAME or "other data" state is always consistent with the update, i.e. the most recent change wins. For example, if you have a node which contains a CNAME rdataset, and then add an MX rdataset to it, then the CNAME rdataset will be deleted. Likewise if you have a node containing an MX rdataset and add a CNAME rdataset, the MX rdataset will be deleted. rdatasetscg|_yrr*selfs r __init__z Node.__init__Ys rnamekwrc tj}|jD]D}t|dkDs|j |j |fi||j dF|j ddS)a"Convert a node to text format.

A node which contains a CNAME or RRSIG(CNAME) is a ``NodeKind.CNAME`` node. A node which contains only "neutral" types, i.e. types allowed to co-exist with a CNAME, is a ``NodeKind.NEUTRAL`` node. The neutral types are NSEC, NSEC3, KEY, and their associated RRSIGS. An empty node is also considered neutral. A node which contains some rdataset which is not a CNAME, RRSIG(CNAME), or a neutral type is a a ``NodeKind.REGULAR`` node. Regular nodes are also commonly referred to as "other data". )r*rrr r r)r.rrOs r rz Node.classify#sMH$$X__hooFDx''' 'rcy)NFr'r-s r is_immutablezNode.is_immutable8sr)"r r!r"r# __slots__r/rr0Namerr?rr9rArErGrIrLrPrNONE rdataclass RdataClassr%boolrr&rWrYr\rerrrhr'rr r)r)Gs  I!CHHMM!c3h!C!(2 &#$(@+.--*<*< '**' ''' '' '  '    'Z+.--*<*< #**# ''# '' #  #    % #R+.--*<*< '**' ''' '' '  ',+CLL,A,A+d+4 ( *drr)c eZdZfdZej j dfdejjdej jdej jde dejjf fd Z ej j dfdejjdej jdej jde dejjd zf fd Zej j fdejjdej jdej jdd fd Zd ejjdd fd Zde fdZxZS) ImmutableNodect|t|jDcgc]!}tj j |#c}|_ycc}wr)superr/tupler*rrImmutableRdataset)r.noder< __class__s r r/zImmutableNode.__init__>sB <@NN KNSS\\ + +C 0N K  Ks&AFrQr r rRrcB|r tdt| |||dSN immutableF) TypeErrorrrrWr.rQr r rRrvs r rWzImmutableNode.find_rdatasetDs) K( (w$WffeDDrNcB|r tdt| |||dSrx)rzrrrYr{s r rYzImmutableNode.get_rdatasetOs) K( (w#GVVUCCrctdNryrz)r.rQr r s r r\zImmutableNode.delete_rdatasetZs  $$rr]ctdr~rrds r rezImmutableNode.replace_rdatasetbs  $$rcy)NTr'r-s r rhzImmutableNode.is_immutableesr)r r!r"r/rrrkrlrmr%rnrr&rWrYr\rerh __classcell__)rvs@r rprp<sx +.--*<*< E** E '' E '' E  E    E+.--*<*< D** D '' D '' D  D    % D+.--*<*< %**% ''% '' %  %%CLL,A,A%d%drrp)r#enumr5typingrr dns.immutablerdns.namedns.rdataclass dns.rdataset dns.rdatatype dns.rrsetrrrNSECNSEC3KEYrruniqueEnumrr)ryrpr'rr rs$0 MM MMMMMMV>tyy> >.rrj)D))r
