Method __hash__ Undocumented
Method __init__
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 flag A <character-string> containing flags to control aspects of the rewriting and interpretation of the fields in the record. Flags are single characters from the set [A-Z0-9]. The case of the alphabetic characters is not significant.
Instance Variable flags Undocumented
Instance Variable order An integer specifying the order in which the NAPTR records MUST be processed to ensure the correct ordering of rules. Low numbers are processed before high numbers.
Instance Variable preference An integer that specifies the order in which NAPTR records with equal "order" values SHOULD be processed, low numbers being processed before high numbers.
Instance Variable regexp A STRING containing a substitution expression that is applied to the original string held by the client in order to construct the next domain name to lookup.
Instance Variable replacement The next NAME to query for NAPTR, SRV, or address records depending on the value of the flags field. This MUST be a fully qualified domain-name.
Instance Variable service Specifies the service(s) available down this rewrite path. It may also specify the particular protocol that is used to talk with a service. A protocol MUST be specified if the flags field states that the NAPTR is terminal.
Instance Variable ttl The maximum number of seconds which this record should be cached.

ttlUndocumented
def decode(self, strio, length=None): (source)
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)
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.
compareAttributes: tuple[str, ...] = (source)
fancybasename: str = (source)

Undocumented

A <character-string> containing flags to control aspects of the rewriting and interpretation of the fields in the record. Flags are single characters from the set [A-Z0-9]. The case of the alphabetic characters is not significant.

At this time only four flags, "S", "A", "U", and "P", are defined.

Undocumented

order: int = (source)
An integer specifying the order in which the NAPTR records MUST be processed to ensure the correct ordering of rules. Low numbers are processed before high numbers.
preference: int = (source)
An integer that specifies the order in which NAPTR records with equal "order" values SHOULD be processed, low numbers being processed before high numbers.
A STRING containing a substitution expression that is applied to the original string held by the client in order to construct the next domain name to lookup.
replacement: Name = (source)
The next NAME to query for NAPTR, SRV, or address records depending on the value of the flags field. This MUST be a fully qualified domain-name.
service: Charstr = (source)
Specifies the service(s) available down this rewrite path. It may also specify the particular protocol that is used to talk with a service. A protocol MUST be specified if the flags field states that the NAPTR is terminal.
The maximum number of seconds which this record should be cached.
