Part of twisted.internet.udp View Source View In Hierarchy
Known subclasses: twisted.internet.udp.MulticastPort, twisted.internet.unix.DatagramPort
Implements interfaces: twisted.internet.interfaces.IListeningPort, twisted.internet.interfaces.ISystemHandle, twisted.internet.interfaces.IUDPTransport
Method | __init__ | Initialize with a numeric port to listen on. |
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 | Reliably write a sequence of data. |
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 | Returns an IPv4Address. |
Method | _bindSocket | Undocumented |
Method | _connectToProtocol | Undocumented |
Method | _loseConnection | Undocumented |
Inherited from BasePort:
Method | createInternetSocket | Undocumented |
Method | doWrite | Raises a RuntimeError |
Inherited from FileDescriptor (via 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 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 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. |
This is called on unserialization, and must be called after creating a server to begin listening on the specified port.
Parameters | datagram | The datagram to be sent. (type: str ) |
addr | A tuple of (stringified dotted-quad IP address, integer port
number); can be None in connected mode. (type: tuple containing str as first element and
int as second element, or None ) |
Currently, this is a convenience method roughly equivalent to:
for chunk in iovec: fd.write(chunk)
It may have a more efficient implementation at a later time or in a different reactor.
As with the write()
method, if a buffer size limit is
reached and a streaming producer is registered, it will be paused until the
buffered data is written to the underlying file descriptor.
If it does not complete immediately, will return Deferred that fires upon completion.
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.
logstr
attribute to be used by
logPrefix
.This indicates the address from which I am connecting.
