twisted.internet.iocpreactor.abstract.FileHandle : API documentation

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.

def stopWriting(self): (source)

Undocumented

def _resumeWriting(self): (source)

Undocumented

def _cbWrite(self, rc, bytes, evt): (source)

Undocumented

def _handleWrite(self, rc, bytes, evt): (source)

Returns false if we should stop writing for now

def doWrite(self): (source)

Undocumented

def writeToHandle(self, buff, evt): (source)

overridden in twisted.internet.iocpreactor.tcp.Connection

Undocumented

def write(self, data): (source)

from twisted.internet.interfaces.IConsumer

overridden in twisted.internet.iocpreactor.tcp.Connection, twisted.internet.iocpreactor.udp.Port

Reliably write some data.

The data is buffered until his file descriptor is ready for writing.

def writeSequence(self, iovec): (source)

from twisted.internet.interfaces.ITransport

overridden in twisted.internet.iocpreactor.tcp.Connection, twisted.internet.iocpreactor.udp.Port

Write a list of 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 string.

def __init__(self, reactor=None): (source)

overridden in twisted.internet.iocpreactor.tcp.Connection, twisted.internet.iocpreactor.udp.Port

Undocumented

def connectionLost(self, reason): (source)

overridden in twisted.internet.iocpreactor.tcp.Connection, twisted.internet.iocpreactor.udp.Port

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 getFileHandle(self): (source)

Undocumented

def loseConnection(self, _connDone=failure.Failure(main.CONNECTION_DONE)): (source)

from twisted.internet.interfaces.ITransport

overridden in twisted.internet.iocpreactor.tcp.Connection, twisted.internet.iocpreactor.udp.Port

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 stopConsuming(self): (source)

Stop consuming data.

This is called when a producer has lost its connection, to tell the consumer to go lose its connection (and break potential circular references).

def resumeProducing(self): (source)

from twisted.internet.interfaces.IPushProducer

Resume producing data.

This tells a producer to re-add itself to the main loop and produce more data for its consumer.

def pauseProducing(self): (source)

from twisted.internet.interfaces.IPushProducer

Pause producing data.

Tells a producer that it has produced too much data to process for the time being, and to stop until resumeProducing() is called.

def stopProducing(self): (source)

from twisted.internet.interfaces.IProducer

Stop producing data.

This tells a producer that its consumer has died, so it must stop producing data for good.

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.

Method	logPrefix	Override this method to insert custom logging behavior. Its return value will be inserted in front of every line. It may be called more times than the number of output lines.
Method	_getLogPrefix	Determine the log prefix to use for messages related to `applicationObject`, which may or may not be an `interfaces.ILoggingContext` provider.
