Implements interfaces: twisted.names.dns.IEncodable

A resource record header.

Class Variable fmt str specifying the byte format of an RR.
Instance Variable name The name about which this reply contains information.
Instance Variable type The query type of the original request.
Instance Variable cls The query class of the original request.
Instance Variable ttl The time-to-live for this record.
Instance Variable payload An object that implements the IEncodable interface
Instance Variable auth A bool indicating whether this RRHeader was parsed from an authoritative message.
Method __init__
Method encode Write a representation of this object to the given file object.
Method decode Reconstruct an object from data read from the given file object.
Method isAuthoritative Undocumented
Method __str__ Undocumented

fmt =
str specifying the byte format of an RR.
name =
The name about which this reply contains information.
type =
The query type of the original request.
cls =
The query class of the original request.
ttl =
The time-to-live for this record.
payload =
An object that implements the IEncodable interface

def __init__(self, name='', type=A, cls=IN, ttl=0, payload=None, auth=False): (source)
ParametersnameThe name about which this reply contains information. (type: bytes)
typeThe query type. (type: int)
clsThe query class. (type: int)
ttlTime to live for this record. (type: int)
payloadA Query Type specific data object. (type: An object implementing IEncodable)
RaisesValueErrorif the ttl is negative.
def encode(self, strio, compDict=None): (source)

Write a representation of this object to the given file object.

ParametersstrioThe stream to which to write bytes (type: File-like object)
compDictA dictionary of backreference addresses that have already been written to this stream and that may be used for compression. (type: dict or None)
def decode(self, strio, length=None): (source)

Reconstruct an object from data read from the given file object.

ParametersstrioThe stream from which bytes may be read (type: File-like object)
lengthThe number of bytes in this RDATA field. Most implementations can ignore this value. Only in the case of records similar to TXT where the total length is in no way encoded in the data is it necessary. (type: int or None)
