Method | `decode` | Reconstruct an object from data read from the given file object.

Class Variable | `showAttributes` | Undocumented
Instance Variable | `hostname` | The domain name of a host that has a server for the cell named by this record.
Instance Variable | `subtype` | In the case of subtype 1, the host has an AFS version 3.0 Volume Location Server for the named AFS cell. In the case of subtype 2, the host has an authenticated name server holding the cell-root directory node for the named DCE/NCA cell.
Instance Variable | `ttl` | The maximum number of seconds which this record should be cached.

def __hash__(self): (source)

def __init__(self, subtype=0, hostname=b'', ttl=None): (source)

Parameters
subtype | Undocumented
hostname:`bytes` or `str` | See `Record_AFSDB.hostname`
ttl | Undocumented

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 object | A seekable buffer from which bytes may be read.
length:`int` or `None` | 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.

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 object | The buffer to write to. It must have a `tell()` method.
compDict:`dict` of `bytes` to `int` r `None` | A 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.
