twisted.protocols.basic.FileSender : API documentation

A producer that sends the contents of a file to a consumer.

This is a helper for protocols that, at some point, will take a file-like object, read its contents, and write them out to the network, optionally performing some transformation on the bytes in between.

Method	beginFileTransfer	Begin transferring a file
Method	resumeProducing	Undocumented
Method	pauseProducing	Undocumented
Method	stopProducing	Stop producing data.

def beginFileTransfer(self, file, consumer, transform=None): (source)

Begin transferring a file

Parameters	file	The file object to read data from (type: Any file-like object )
	consumer	The object to write data to (type: Any implementor of IConsumer )
	transform	A callable taking one string argument and returning the same. All bytes read from the file are passed through this before being written to the consumer.
Returns	A deferred whose callback will be invoked when the file has been completely written to the consumer. The last byte written to the consumer is passed to the callback. (type: `Deferred` )

def resumeProducing(self): (source)

Undocumented

def pauseProducing(self): (source)

Undocumented

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.
