Class Variable	fmt	`str` specifying the byte format of an RR.
Instance Variable	name	The name about which this reply contains information. (type: `Name`)
Instance Variable	type	The query type of the original request. (type: `int`)
Instance Variable	cls	The query class of the original request.
Instance Variable	ttl	The time-to-live for this record. (type: `int`)
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.

fmt =

str specifying the byte format of an RR.

name =

The name about which this reply contains information. (type: Name)

type =

The query type of the original request. (type: int)

cls =

The query class of the original request.

ttl =

The time-to-live for this record. (type: int)

payload =

An object that implements the IEncodable interface

auth =

A bool indicating whether this RRHeader was parsed from an authoritative message.

def __init__(self, name='', type=A, cls=IN, ttl=0, payload=None, auth=False): (source)

Parameters	name	See `RRHeader.name` (type: `bytes` or `unicode`)
	type	The query type. (type: `int`)
	cls	The query class. (type: `int`)
	ttl	Time to live for this record. (type: `int`)
	payload	A Query Type specific data object. (type: An object implementing `IEncodable`)
Raises	ValueError	if the ttl is negative.

def encode(self, strio, compDict=None): (source)

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

Parameters	strio	The stream to which to write bytes (type: File-like object)
	compDict	A 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.

Parameters	strio	The stream from which bytes may be read (type: File-like object)
	length	The 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`)

def isAuthoritative(self): (source)

Undocumented

def __str__(self): (source)
