t.i.u.DatagramPort(_UNIXPort, udp.Port) : class documentation

Part of twisted.internet.unix View Source View In Hierarchy

Known subclasses: twisted.internet.unix.ConnectedDatagramPort

Implements interfaces: twisted.internet.interfaces.IUNIXDatagramTransport

Datagram UNIX port, listening for packets.
Method __init__ Initialize with address to listen on.
Method __repr__ Undocumented
Method write Write a datagram.
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:

Method getHost Returns a UNIXAddress.

Inherited from Port:

Instance Variable maxThroughput Maximum number of bytes read in one event loop iteration.
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 writeSequence Reliably write a sequence of data.
Method connect 'Connect' to remote server.
Method stopListening Undocumented
Method loseConnection Close the connection at the next available opportunity.
Method logPrefix Return the prefix to log with.
Method getHost Returns an IPv4Address.
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

Inherited from BasePort (via Port):

Method createInternetSocket Undocumented
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 Undocumented
Method readConnectionLost Undocumented
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 Undocumented
Method pauseProducing Undocumented
Method stopProducing Undocumented
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 or int)
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.
def __init__(self, addr, proto, maxPacketSize=8192, mode=438, reactor=None): (source)
Initialize with address to listen on.
def __repr__(self): (source)
def _bindSocket(self): (source)
Prepare and assign a socket.socket instance to self.socket.

Either creates a new SOCK_DGRAM socket.socket bound to self.interface and self.port or takes an existing socket.socket provided via the interfaces.IReactorSocket.adoptDatagramPort interface.

def write(self, datagram, address): (source)
Write a datagram.
def connectionLost(self, reason=None): (source)
Cleans up my socket.
def setLogStr(self): (source)
Initialize the logstr attribute to be used by logPrefix.
