  __gt__(self, other)
(inherited from Rdata)
  __le__(self, other)
(inherited from Rdata)
  __lt__(self, other)
(inherited from Rdata)
  __ne__(self, other)
(inherited from Rdata)
a new object with type S, a subtype of T __new__(S, ...)
  __repr__(self)
(inherited from Rdata)
  __str__(self)
(inherited from Rdata)
  choose_relativity(self, origin, relativize)
Convert any domain names in the rdata to the specified relativization.
int covers(self)
DNS SIG/RRSIG rdatas apply to a specific type; this type is returned by the covers() function.
int extended_rdatatype(self)
Return a 32-bit type value, the least significant 16 bits of which are the ordinary DNS type, and the upper 16 bits of which are the "covered" type, if any. (inherited from Rdata)
string to_text(self, origin, relativize, **kw)
Convert an rdata to text format.
string to_wire(self, file, compress, origin)
Convert an rdata to wire format.

Method Details

__new__(S, ...)

Returns:
a new object with type S, a subtype of T

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)
