Implements interfaces: twisted.names.dns.IEncodableRecord

Marks the start of a zone of authority.

This record describes parameters which are shared by all records within a particular zone.

Method __hash__ Undocumented
Method __init__ No summary
Method decode Reconstruct an object from data read from the given file object.
Method encode Write a representation of this object to the given file object.
Class Variable compareAttributes Undocumented
Class Variable fancybasename Undocumented
Class Variable showAttributes Undocumented
Instance Variable expire A 32 bit time value that specifies the upper limit on the time interval that can elapse before the zone is no longer authoritative.
Instance Variable minimum The unsigned 32 bit minimum TTL field that should be exported with any RR from this zone.
Instance Variable mname The domain-name of the name server that was the original or primary source of data for this zone.
Instance Variable refresh A 32 bit time interval before the zone should be refreshed.
Instance Variable retry A 32 bit time interval that should elapse before a failed refresh should be retried.
Instance Variable rname A domain-name which specifies the mailbox of the person responsible for this zone.
Instance Variable serial The unsigned 32 bit version number of the original copy of the zone. Zone transfers preserve this value. This value wraps and should be compared using sequence space arithmetic.
Instance Variable ttl The default TTL to use for records served from this zone.

def decode(self, strio, length=None): (source)
from twisted.names.dns.IEncodable

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

Parameters
strio:File-like objectA seekable buffer from which bytes may be read.
length:int or NoneThe 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.
def encode(self, strio, compDict=None): (source)
from twisted.names.dns.IEncodable

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

Parameters
strio:File-like objectThe buffer to write to. It must have a tell() method.
compDict:dict of bytes to int r NoneA mapping of names to byte offsets that have already been written to the buffer, which may be used for compression (see RFC 1035 section 4.1.4). When None, encode without compression.

expire: int = (source)

A 32 bit time value that specifies the upper limit on the time interval that can elapse before the zone is no longer authoritative.

minimum: int = (source)

The unsigned 32 bit minimum TTL field that should be exported with any RR from this zone.

mname: Name = (source)

The domain-name of the name server that was the original or primary source of data for this zone.

refresh: int = (source)

A 32 bit time interval before the zone should be refreshed.

retry: int = (source)

A 32 bit time interval that should elapse before a failed refresh should be retried.

rname: Name = (source)

A domain-name which specifies the mailbox of the person responsible for this zone.

serial: int = (source)

The unsigned 32 bit version number of the original copy of the zone. Zone transfers preserve this value. This value wraps and should be compared using sequence space arithmetic.

ttl: int = (source)

The default TTL to use for records served from this zone.
