class twisted.names.dns.Record_SRV(tputil.FancyEqMixin, tputil.FancyStrMixin): (source)

Implements interfaces: twisted.names.dns.IEncodableRecord

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

This is an experimental record type.

See Also http://www.faqs.org/rfcs/rfc2782.html

Instance Variable	priority	The priority of this target host. A client MUST attempt to contact the target host with the lowest-numbered priority it can reach; target hosts with the same priority SHOULD be tried in an order defined by the weight field.
Instance Variable	weight	Specifies a relative weight for entries with the same priority. Larger weights SHOULD be given a proportionately higher probability of being selected.
Instance Variable	port	The port on this target host of this service.
Instance Variable	target	The domain name of the target host. There MUST be one or more address records for this name, the name MUST NOT be an alias (in the sense of RFC 1034 or RFC 2181). Implementors are urged, but not required, to return the address record(s) in the Additional Data section. Unless and until permitted by future standards action, name compression is not to be used for this field.
Instance Variable	ttl	The maximum number of seconds which this record should be cached.
Class Variable	fancybasename	Undocumented
Class Variable	compareAttributes	Undocumented
Class Variable	showAttributes	Undocumented
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.

priority = (source)

The priority of this target host. A client MUST attempt to contact the target host with the lowest-numbered priority it can reach; target hosts with the same priority SHOULD be tried in an order defined by the weight field.

(type: int)

weight = (source)

Specifies a relative weight for entries with the same priority. Larger weights SHOULD be given a proportionately higher probability of being selected.

(type: int)

port = (source)

The port on this target host of this service.

(type: int)

target = (source)

The domain name of the target host. There MUST be one or more address records for this name, the name MUST NOT be an alias (in the sense of RFC 1034 or RFC 2181). Implementors are urged, but not required, to return the address record(s) in the Additional Data section. Unless and until permitted by future standards action, name compression is not to be used for this field.

(type: Name)

ttl = (source)

The maximum number of seconds which this record should be cached.

(type: int)

fancybasename = (source)

Undocumented

(type: str)

compareAttributes = (source)

overrides twisted.python.util.FancyEqMixin.compareAttributes

Undocumented

(type: tuple[str, ...])

showAttributes = (source)

overrides twisted.python.util.FancyStrMixin.showAttributes

Undocumented

(type: tuple)

def __init__(self, priority=0, weight=0, port=0, target=b'', ttl=None): (source)

Parameters	priority	Undocumented
	weight	Undocumented
	port	Undocumented
	target	See `Record_SRV.target` (type: `bytes` or `str`)
	ttl	Undocumented

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 buffer to write to. It must have a `tell()` method. (type: File-like object)
	compDict	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. (type: `dict` of `bytes` to `int` r `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	A seekable buffer 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`)

def __hash__(self): (source)

Undocumented
