Method _cbRead Undocumented
Method _handleRead Returns False if we should stop reading for now
Method _closeWriteConnection Undocumented
Method _resumeWriting Undocumented

Inherited from _ConsumerMixin (via FileHandle):

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 FileHandle):

Method _getLogPrefix Determine the log prefix to use for messages related to applicationObject, which may or may not be an interfaces.ILoggingContext provider.
addressFamily =
socket.AF_INET or socket.AF_INET6, depending on whether this port is listening on an IPv4 address or an IPv6 address.
def __init__(self, port, proto, interface='', maxPacketSize=8192, reactor=None): (source)

Initialize with a numeric port to listen on.

def _setAddressFamily(self): (source)

Resolve address family for the socket.

def __repr__(self): (source)
Undocumented
def getHandle(self): (source)

Return a socket object.

def startListening(self): (source)

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 createSocket(self): (source)
def _bindSocket(self): (source)
Undocumented
def _connectToProtocol(self): (source)
Undocumented
def cbRead(self, rc, data, evt): (source)
Undocumented
def handleRead(self, rc, data, evt): (source)
Undocumented
def write(self, datagram, addr=None): (source)

Write a datagram.

Parametersaddrshould be a tuple (ip, port), can be None in connected mode.
def writeSequence(self, seq, addr): (source)

Write an iterable of byte strings to the physical connection.

If possible, make sure that all of the data is written to the socket at once, without first copying it all into a single byte string.

ParametersdataThe data to write. (type: an iterable of bytes)
def connect(self, host, port): (source)

'Connect' to remote server.

def _loseConnection(self): (source)
Undocumented
def stopListening(self): (source)

Stop listening on this port.

If it does not complete immediately, will return Deferred that fires upon completion.

def loseConnection(self): (source)

Close the connection at the next available opportunity.

Call this to cause this FileDescriptor to lose its connection. It will first write any data that it has buffered.

If there is data buffered yet to be written, this method will cause the transport to lose its connection as soon as it's done flushing its write buffer. If you have a producer registered, the connection won't be closed until the producer is finished. Therefore, make sure you unregister your producer when it's finished, or the connection will never close.

def connectionLost(self, reason=None): (source)
def setLogStr(self): (source)

Initialize the logstr attribute to be used by logPrefix.

def logPrefix(self): (source)

Returns the name of my class, to prefix log entries with.

def getHost(self): (source)

Return the local address of the UDP connection

Returnsthe local address of the UDP connection (type: IPv4Address or IPv6Address)
def setBroadcastAllowed(self, enabled): (source)

Set whether this port may broadcast. This is disabled by default.

ParametersenabledWhether the port may broadcast. (type: bool)
def getBroadcastAllowed(self): (source)

Checks if broadcast is currently allowed on this port.

ReturnsWhether this port may broadcast. (type: bool)
