twisted.names.dns.Record_NAPTR(tputil.FancyEqMixin, tputil.FancyStrMixin) class documentation

Part of twisted.names.dns View Source (View In Hierarchy)

Implements interfaces: twisted.names.dns.IEncodable, twisted.names.dns.IRecord

The location of the server(s) for a specific protocol and domain.

See Alsohttp://www.faqs.org/rfcs/rfc2915.html
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. (type: int)
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. (type: int)
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.

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

(type: Charstr)
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. (type: Charstr)
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. (type: Charstr)
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. (type: Name)
Instance Variable ttl The maximum number of seconds which this record should be cached. (type: int)

ParametersreplacementSee Record_NAPTR.replacement (type: bytes or unicode)
def encode(self, strio, compDict=None): (source)
from twisted.names.dns.IEncodable

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

ParametersstrioThe stream to which to write bytes (type: File-like object)
compDictA 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)
from twisted.names.dns.IEncodable

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

ParametersstrioThe stream from which bytes may be read (type: File-like object)
lengthThe 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)
