Method unregisterProducer Stop consuming data from a producer, without disconnecting.
Instance Variable streamingProducer bool or int

Inherited from _LogOwner (via FileHandle):

def __init__(self, port, proto, interface='', maxPacketSize=8192, reactor=None): (source)
Initialize with a numeric port to listen on.
def __repr__(self): (source)

Undocumented

Returns
strUndocumented
def cbRead(self, rc, data, evt): (source)

Undocumented

def connect(self, host, port): (source)
'Connect' to remote server.
def connectionLost(self, reason=None): (source)
def createSocket(self): (source)
def getBroadcastAllowed(self): (source)
Checks if broadcast is currently allowed on this port.
Returns
boolWhether this port may broadcast.
def getHandle(self): (source)
Return a socket object.
def getHost(self): (source)
Return the local address of the UDP connection
Returns
IPv4Address or IPv6Addressthe local address of the UDP connection
def handleRead(self, rc, data, evt): (source)

Undocumented

def logPrefix(self): (source)
Returns the name of my class, to prefix log entries with.
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 setBroadcastAllowed(self, enabled): (source)
Set whether this port may broadcast. This is disabled by default.
Parameters
enabled:boolWhether the port may broadcast.
def setLogStr(self): (source)
Initialize the logstr attribute to be used by logPrefix.
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 stopListening(self): (source)

Stop listening on this port.

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

def write(self, datagram, addr=None): (source)
Write a datagram.
Parameters
datagramUndocumented
addrshould 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.

Parameters
seqUndocumented
addrUndocumented
dataThe data to write.
