Instance Variable TLS False to indicate the connection is in normal TCP mode, True to indicate that TLS has been started and that operations must be routed through the TLSMemoryBIOProtocol instance.
Method __init__ Undocumented
Method getHandle Return a system- and reactor-specific handle.

Method startTLS
Method write Write some data, either directly to the underlying handle or, if TLS has been started, to the TLSMemoryBIOProtocol for it to encrypt and send.
Method writeSequence Write some data, either directly to the underlying handle or, if TLS has been started, to the TLSMemoryBIOProtocol for it to encrypt and send.
Method loseConnection Close the underlying handle or, if TLS has been started, first shut it down.

Method unregisterProducer Unregister a producer.
Method _closeWriteConnection Undocumented

Inherited from FileHandle:

Method startReading Undocumented
Method stopReading Undocumented
Method doRead Undocumented
Method loseWriteConnection Undocumented
Method writeConnectionLost Indicates write connection was lost.
Method startWriting No summary
Method stopWriting Undocumented
Method doWrite Undocumented
Method getFileHandle Undocumented
Method stopConsuming Stop consuming data.
Method resumeProducing Resume producing data.
Method pauseProducing Pause producing data.
Method stopProducing Stop producing data.
Method _resumeReading Undocumented
Method _dispatchData Dispatch previously read data. Return True if self.reading and we don't have any more data
Method _cbRead Undocumented
Method _handleRead Returns False if we should stop reading for now
Method _resumeWriting Undocumented
Method _cbWrite Undocumented
Method _handleWrite Returns false if we should stop writing for now

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

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.

Inherited from _SocketCloser:

Instance Variable _shouldShutdown Set to True if shutdown should be called before calling close on the underlying socket. (type: bool)
Method _closeSocket Undocumented

Inherited from _AbortingMixin:

Method abortConnection Aborts the connection immediately, dropping any buffered data.
Instance Variable _aborting Set to True when abortConnection is called. (type: bool)
TLS =
False to indicate the connection is in normal TCP mode, True to indicate that TLS has been started and that operations must be routed through the TLSMemoryBIOProtocol instance.
def getHandle(self): (source)

Return a system- and reactor-specific handle.

This might be a socket.socket() object, or some other type of object, depending on which reactor is being used. Use and manipulate at your own risk.

This might be used in cases where you want to set specific options not exposed by the Twisted APIs.

def dataReceived(self, rbuffer): (source)
ParametersrbufferData received. (type: bytes or bytearray)
def readFromHandle(self, bufflist, evt): (source)

Read into the given buffers from this handle.

Parametersbuffthe buffers to read into (type: list of objects implementing the read/write buffer protocol)
evtan IOCP Event object
Returnstuple (return code, number of bytes read)
def writeToHandle(self, buff, evt): (source)

Send buff to current file handle using _iocp.send. The buffer sent is limited to a size of self.SEND_LIMIT.

def _closeWriteConnection(self): (source)
def readConnectionLost(self, reason): (source)
def connectionLost(self, reason): (source)

The connection was lost.

This is called when the connection on a selectable object has been lost. It will be called whether the connection was closed explicitly, an exception occurred in an event handler, or the other end of the connection closed it first.

Clean up state here, but make sure to call back up to FileDescriptor.

def logPrefix(self): (source)

Return the prefix to log with when I own the logging thread.

def getTcpNoDelay(self): (source)

Return if TCP_NODELAY is enabled.

def setTcpNoDelay(self, enabled): (source)

Enable/disable TCP_NODELAY.

Enabling TCP_NODELAY turns off Nagle's algorithm. Small packets are sent sooner, possibly at the expense of overall throughput.

def getTcpKeepAlive(self): (source)

Return if SO_KEEPALIVE is enabled.

def setTcpKeepAlive(self, enabled): (source)

Enable/disable SO_KEEPALIVE.

Enabling SO_KEEPALIVE sends packets periodically when the connection is otherwise idle, usually once every two hours. They are intended to allow detection of lost peers in a non-infinite amount of time.

def startTLS(self, contextFactory, normal=True): (source)
def write(self, data): (source)

Write some data, either directly to the underlying handle or, if TLS has been started, to the TLSMemoryBIOProtocol for it to encrypt and send.

See Alsotwisted.internet.interfaces.ITransport.write
def writeSequence(self, iovec): (source)

Write some data, either directly to the underlying handle or, if TLS has been started, to the TLSMemoryBIOProtocol for it to encrypt and send.

See Alsotwisted.internet.interfaces.ITransport.writeSequence
def loseConnection(self, reason=None): (source)
def registerProducer(self, producer, streaming): (source)

Register a producer.

If TLS is enabled, the TLS connection handles this.

def unregisterProducer(self): (source)

Unregister a producer.

If TLS is enabled, the TLS connection handles this.
