Detailed Description

Base class for all DNS rdata types.

Definition at line 95 of file rdata.py.

Constructor & Destructor Documentation

◆ __init__()

def dns.rdata.Rdata.__init__ (   self,
Initialize an rdata.

*rdclass*, an ``int`` is the rdataclass of the Rdata.
*rdtype*, an ``int`` is the rdatatype of the Rdata.

◆ covers()

def dns.rdata.Rdata.covers (   self)
Return the type a Rdata covers.

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 an ``int``.

Reimplemented in dns.rdtypes.ANY.RRSIG.RRSIG.

◆ extended_rdatatype()

def dns.rdata.Rdata.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.

Returns an ``int``.

Raises various exceptions if there are problems.

Returns ``None``.
