Usually this value is dns.rdatatype.NONE, but if the rdtype is dns.rdatatype.SIG or dns.rdatatype.RRSIG, then the covers value will be the rdata type the SIG/RRSIG covers. The library treats the SIG and RRSIG types as if they were a family of types, e.g. RRSIG(A), RRSIG(NS), RRSIG(SOA). This makes RRSIGs much easier to work with than if RRSIGs covering different rdata types were aggregated into a single RRSIG rdataset. @type covers: int @param create: If True, create the rdataset if it is not found. @type create: bool @raises KeyError: An rdataset of the desired type and class does not exist and I{create} is not True. @rtype: dns.rdataset.Rdataset object ( R t matcht KeyErrort dnst rdatasett Rdatasett append( R t rdclasst rdtypet coverst createR ( ( s. /usr/lib64/python2.7/site-packages/dns/node.pyt find_rdatasetT s c C s: y | j | | | | � } Wn t k r5 d } n X| S( sE Get an rdataset matching the specified properties in the current node.
