Method Summary
  __init__(self, rdclass, rdtype, type_covered, algorithm, labels, original_ttl, expiration, inception, key_tag, signer, signature)
  choose_relativity(self, origin, relativize)
Convert any domain names in the rdata to the specified relativization.
int covers(self)

(Class method)
  from_wire(cls, rdclass, rdtype, wire, current, rdlen, origin)
(Class method)
string to_text(self, origin, relativize, **kw)
Convert an rdata to text format.

Instance Method Details

choose_relativity(self, origin=None, relativize=True)

Convert any domain names in the rdata to the specified relativization.
Overrides:
dns.rdata.Rdata.choose_relativity (inherited documentation)

covers(self)

DNS SIG/RRSIG rdatas apply to a specific type; this type is returned by the covers() function. If the rdata type is not SIG or RRSIG, dns.rdatatype.NONE is returned. This is useful when creating rdatasets, allowing the rdataset to contain only RRSIGs of a particular type, e.g. RRSIG(NS).
Returns:
int
Overrides:
dns.rdata.Rdata.covers (inherited documentation)

to_text(self, origin=None, relativize=True, **kw)

Convert an rdata to text format.
Returns:
string
Overrides:
dns.rdata.Rdata.to_text (inherited documentation)

to_wire(self, file, compress=None, origin=None)

Convert an rdata to wire format.
Returns:
string
Overrides:
dns.rdata.Rdata.to_wire (inherited documentation)
