twisted.internet.unix.ConnectedDatagramPort : API documentation

Method	__init__	Initialize with address to listen on.
Method	startListening	Create and bind my socket, and begin listening on it.
Method	connectionFailed	Called when a connection fails. Stop listening on the socket.
Method	doRead	Called when my socket is ready for reading.
Method	write	Write a datagram.
Method	getPeer	Get the remote address of this connection.

Inherited from DatagramPort:

Method	__repr__	Undocumented
Method	connectionLost	Cleans up my socket.
Method	setLogStr	Initialize the `logstr` attribute to be used by `logPrefix`.
Method	_bindSocket	Prepare and assign a `socket.socket` instance to `self.socket`.

Inherited from _UNIXPort (via DatagramPort):

Method

getHost

Returns a UNIXAddress.

Inherited from Port (via DatagramPort):

Instance Variable	maxThroughput	Maximum number of bytes read in one event loop iteration.
Instance Variable	addressFamily	`socket.AF_INET` or `socket.AF_INET6`, depending on whether this port is listening on an IPv4 address or an IPv6 address.
Method	getHandle	Return a socket object.
Method	writeSequence	Write a datagram constructed from an iterable of `bytes`.
Method	connect	'Connect' to remote server.
Method	stopListening	Stop listening on this port.
Method	loseConnection	Close the connection at the next available opportunity.
Method	logPrefix	Return the prefix to log with.
Method	getHost	Return the local address of the UDP connection
Method	setBroadcastAllowed	Set whether this port may broadcast. This is disabled by default.
Method	getBroadcastAllowed	Checks if broadcast is currently allowed on this port.
Instance Variable	_realPortNumber	Actual port number being listened on. The value will be `None` until this `Port` is listening.
Instance Variable	_preexistingSocket	If not `None`, a `socket.socket` instance which was created and initialized outside of the reactor and will be used to listen for connections (instead of a new socket being created by this `Port`).
Class Method	_fromListeningDescriptor	Create a new `Port` based on an existing listening SOCK_DGRAM socket.
Method	_connectToProtocol	Undocumented
Method	_loseConnection	Undocumented
Method	_setAddressFamily	Resolve address family for the socket.

Inherited from BasePort (via DatagramPort, Port):

Method	createInternetSocket	Undocumented
Method	doWrite	Raises a RuntimeError

Inherited from FileDescriptor (via DatagramPort, Port, BasePort):

Method	writeSomeData	Write as much as possible of the given data, immediately.
Method	writeConnectionLost	Indicates write connection was lost.
Method	readConnectionLost	Indicates read connection was lost.
Method	loseWriteConnection	Undocumented
Method	stopReading	Stop waiting for read availability.
Method	stopWriting	Stop waiting for write availability.
Method	startReading	Start waiting for read availability.
Method	startWriting	Start waiting for write availability.
Method	stopConsuming	Stop consuming data.
Method	resumeProducing	Resume producing data.
Method	pauseProducing	Pause producing data.
Method	stopProducing	Stop producing data.
Method	fileno	File Descriptor number for select().
Method	_postLoseConnection	Called after a loseConnection(), when all data has been written.
Method	_closeWriteConnection	Undocumented
Method	_isSendBufferFull	Determine whether the user-space send buffer for this transport is full or not.
Method	_maybePauseProducer	Possibly pause a producer, if there is one and the send buffer is full.

Inherited from _ConsumerMixin (via DatagramPort, Port, BasePort, FileDescriptor):

Instance Variable	producer	`None` if no producer is registered, otherwise the registered producer.
Instance Variable	producerPaused	A flag indicating whether the producer is currently paused. (type: `bool`)
Instance Variable	streamingProducer 0	A flag indicating whether the producer was registered as a streaming (ie push) producer or not (ie a pull producer). This will determine whether the consumer may ever need to pause and resume it, or if it can merely call `resumeProducing` on it when buffer space is available.
Instance Variable	streamingProducer	`bool` or `int`
Method	registerProducer	Register to receive data from a producer.
Method	unregisterProducer	Stop consuming data from a producer, without disconnecting.

Inherited from _LogOwner (via DatagramPort, Port, BasePort, FileDescriptor):

Method _getLogPrefix Determine the log prefix to use for messages related to applicationObject, which may or may not be an interfaces.ILoggingContext provider.

def __init__(self, addr, proto, maxPacketSize=8192, mode=438, bindAddress=None, reactor=None): (source)

overrides twisted.internet.unix.DatagramPort.__init__

Initialize with address to listen on.

def startListening(self): (source)

from twisted.internet.interfaces.IListeningPort

overrides twisted.internet.udp.Port.startListening

Create and bind my socket, and begin listening on it.

This is called on unserialization, and must be called after creating a server to begin listening on the specified port.

def connectionFailed(self, reason): (source)

Called when a connection fails. Stop listening on the socket.

Parameters reason Why the connection failed. (type: Failure)

def doRead(self): (source)

from twisted.internet.interfaces.IReadDescriptor

overrides twisted.internet.udp.Port.doRead

Called when my socket is ready for reading.

def write(self, data): (source)

from twisted.internet.interfaces.IUNIXDatagramTransport

overrides twisted.internet.unix.DatagramPort.write

Write a datagram.

def getPeer(self): (source)

from twisted.internet.interfaces.ITransport

Get the remote address of this connection.

Treat this method with caution. It is the unfortunate result of the CGI and Jabber standards, but should not be considered reliable for the usual host of reasons; port forwarding, proxying, firewalls, IP masquerading, etc.

Returns An IAddress provider.
