Method	getOutgoingInterface	Undocumented
Method	setOutgoingInterface	Returns Deferred of success.
Method	getLoopbackMode	Undocumented
Method	setLoopbackMode	Undocumented

Method	setTTL	Undocumented
Method	joinGroup	Join a multicast group. Returns Deferred of success.
Method	leaveGroup	Leave multicast group, return Deferred of success.

Method	_joinAddr2	Undocumented

Inherited from Port:

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	__repr__	Undocumented
Method	getHandle	Return a socket object.
Method	startListening	Create and bind my socket, and begin listening on it.
Method	doRead	Called when my socket is ready for reading.
Method	write	Write a datagram.
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	connectionLost	Cleans up my socket.
Method	setLogStr	Initialize the logstr attribute to be used by logPrefix.
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	_bindSocket	Prepare and assign a socket.socket instance to self.socket.
Method	_connectToProtocol	Undocumented
Method	_loseConnection	Undocumented
Method	_setAddressFamily	Resolve address family for the socket.

Inherited from BasePort (via Port):

Method

doWrite

Raises a RuntimeError

Inherited from FileDescriptor (via 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 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 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.
