Method pauseProducing Pause producing data.
Method resumeProducing Resume producing data.
Method startReading Undocumented
Method startWriting Override in a subclass to cause the reactor to monitor this selectable for write events. This will be called once in unregisterProducer if loseConnection has previously been called, so that the connection can actually close.

Inherited from _ConsumerMixin (via FileHandle):

Instance Variable streamingProducer bool or int

Inherited from _LogOwner (via FileHandle, _ConsumerMixin):

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 (via FileHandle, _ConsumerMixin, _LogOwner):

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

Inherited from _AbortingMixin (via FileHandle, _ConsumerMixin, _LogOwner, _SocketCloser):

Method abortConnection Aborts the connection immediately, dropping any buffered data.
Instance Variable _aborting Set to True when abortConnection is called.
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 dataReceived(self, rbuffer): (source)
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 getTcpKeepAlive(self): (source)

Return if SO_KEEPALIVE is enabled.

def getTcpNoDelay(self): (source)

Return if TCP_NODELAY is enabled.

def logPrefix(self): (source)

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

def loseConnection(self, reason=None): (source)
def readFromHandle(self, bufflist, evt): (source)

Read into the given buffers from this handle.

Parameters
bufflist:list of objects implementing the read/write buffer protocolthe buffers to read into
evtan IOCP Event object
Returns
tuple (return code, number of bytes read)
def registerProducer(self, producer, streaming): (source)

Register a producer.

If TLS is enabled, the TLS connection handles this.

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

Unregister a producer.

If TLS is enabled, the TLS connection handles this.

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 Also
twisted.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 Also
twisted.internet.interfaces.ITransport.writeSequence
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.

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.

Value
False
protocol = (source)
