class MultipleRangeStaticProducer(StaticProducer): (source)

Constructor: MultipleRangeStaticProducer(request, fileObject, rangeInfo)

View In Hierarchy

A StaticProducer that writes several chunks of a file to the request.

Method __init__ Initialize the instance.
Method resumeProducing Produce data for the consumer a single time.
Method start Undocumented
Instance Variable partBoundary Undocumented
Instance Variable rangeInfo Undocumented
Instance Variable rangeIter Undocumented
Method _nextRange Undocumented
Instance Variable _partBytesWritten Undocumented
Instance Variable _partSize Undocumented

Inherited from StaticProducer:

Method stopProducing Stop producing data.
Instance Variable fileObject The file the contents of which to write to the request.
Instance Variable request The IRequest to write the contents of the file to.
def __init__(self, request, fileObject, rangeInfo): (source)
overrides twisted.web.static.StaticProducer.__init__

Initialize the instance.

Parameters
requestSee StaticProducer.
fileObjectSee StaticProducer.
rangeInfo

A list of tuples [(boundary, offset, size)] where:

  • boundary will be written to the request first.
  • offset the offset into the file of chunk to write.
  • size the size of the chunk to write.
def resumeProducing(self): (source)
from twisted.internet.interfaces.IPullProducer
overrides twisted.web.static.StaticProducer.resumeProducing

Produce data for the consumer a single time.

This tells a producer to produce data for the consumer once (not repeatedly, once only). Typically this will be done by calling the consumer's write method a single time with produced data. The producer should produce data before returning from resumeProducing(), that is, it should not schedule a deferred write.
