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.
