twisted.spread.util.FilePager

def __init__(self, collector, fd, *args, callback=None, **kw):

overrides twisted.spread.util.Pager.__init__

Create a pager with a Reference to a remote collector and an optional callable to invoke upon completion.

def startProducing(self, fd):

Undocumented

def registerProducer(self, producer, streaming):

from twisted.internet.interfaces.IConsumer

Register to receive data from a producer.

This sets self to be a consumer for a producer. When this object runs out of data (as when a send(2) call on a socket succeeds in moving the last data from a userspace buffer into a kernelspace buffer), it will ask the producer to resumeProducing().

For IPullProducer providers, resumeProducing will be called once each time data is required.

For IPushProducer providers, pauseProducing will be called whenever the write buffer fills up and resumeProducing will only be called when it empties. The consumer will only call resumeProducing to balance a previous pauseProducing call; the producer is assumed to start in an un-paused state.

Parameters	streaming	`True` if `producer` provides `IPushProducer`, `False` if `producer` provides `IPullProducer`. (type: `bool`)
Returns	`None`
Raises	RuntimeError	If a producer is already registered.

def unregisterProducer(self):

from twisted.internet.interfaces.IConsumer

Stop consuming data from a producer, without disconnecting.

def write(self, chunk):

from twisted.internet.interfaces.IConsumer

The producer will write data by calling this method.

The implementation must be non-blocking and perform whatever buffering is necessary. If the producer has provided enough data for now and it is a IPushProducer, the consumer may call its pauseProducing method.

def sendNextPage(self):

overrides twisted.spread.util.Pager.sendNextPage

Get the first chunk read and send it to collector.

Method	stillPaging	(internal) Method called by Broker.
Method	nextPage	Override this to return an object to be sent to my collector.
Method	stopPaging	Call this when you're done paging.

Method	__init__	Create a pager with a Reference to a remote collector and an optional callable to invoke upon completion.
Method	startProducing	Undocumented
Method	registerProducer	Register to receive data from a producer.
Method	unregisterProducer	Stop consuming data from a producer, without disconnecting.
Method	write	The producer will write data by calling this method.
Method	sendNextPage	Get the first chunk read and send it to collector.
