__init__(self, rdclass, rdtype, type_covered, algorithm, labels, original_ttl, expiration, inception, key_tag, signer, signature)
Initialize an rdata.

source code

int

covers(self)
DNS SIG/RRSIG rdatas apply to a specific type; this type is returned by the covers() function.

string

to_text(self, origin=None, relativize=True, **kw)
Convert an rdata to text format.

source code

string

to_wire(self, file, compress=None, origin=None)
Convert an rdata to wire format.

source code

choose_relativity(self, origin=None, relativize=True)
Convert any domain names in the rdata to the specified relativization.

Method Details

[hide private]

init(self, rdclass, rdtype, type_covered, algorithm, labels, original_ttl, expiration, inception, key_tag, signer, signature)
(Constructor)

source code

Initialize an rdata.

Parameters:

rdclass - The rdata class
rdtype - The rdata type

Overrides: object.__init__

(inherited documentation)

covers(self)

source code

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: rdata.Rdata.covers: (inherited documentation)
