twisted.names.dns.Record_NAPTR : API documentation

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

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

See Also http://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`)
Method	__init__
Method	encode	Write a representation of this object to the given file object.
Method	decode	Reconstruct an object from data read from the given file object.

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)

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)

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)

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)

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)

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)

ttl =

The maximum number of seconds which this record should be cached. (type: int)

def __init__(self, order=0, preference=0, flags='', service='', regexp='', replacement='', ttl=None): (source)

Parameters replacement See 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.

Parameters	strio	The stream to which to write bytes (type: File-like object)
	compDict	A 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.

Parameters	strio	The stream from which bytes may be read (type: File-like object)
	length	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. (type: `int` or `None`)
