t.w.s.CompoundStream(object) : class documentation

Part of twisted.web2.stream View Source View In Hierarchy

Implements interfaces: twisted.web2.stream.IByteStream, twisted.web2.stream.ISendfileableStream

A stream which is composed of many other streams.

Call addStream to add substreams.

Method	__init__	Undocumented
Method	addStream	Add a stream to the output
Method	read	Read some data.
Method	split	Split this stream into two, at byte position 'point'.
Method	close	Prematurely close this stream. Should also cause further reads to return None. Additionally, .length should be set to 0.
Method	_gotFailure	Undocumented
Method	_gotRead	Undocumented

def __init__(self, buckets=()): (source)

Undocumented

def addStream(self, bucket): (source)

Add a stream to the output

def read(self, sendfile=False): (source)

from twisted.web2.stream.IByteStream

Read some data.

Returns an object conforming to the buffer interface, or if there is no more data available, returns None. Can also return a Deferred resulting in one of the above.

Errors may be indicated by exception or by a Deferred of a Failure.

def _gotFailure(self, f): (source)

Undocumented

def _gotRead(self, result, sendfile): (source)

Undocumented

def split(self, point): (source)

from twisted.web2.stream.IByteStream

Split this stream into two, at byte position 'point'.

Returns a tuple of (before, after). After calling split, no other methods should be called on this stream. Doing so will have undefined behavior.

If you cannot implement split easily, you may implement it as:

   return fallbackSplit(self, point)

def close(self): (source)

from twisted.web2.stream.IByteStream

Prematurely close this stream. Should also cause further reads to return None. Additionally, .length should be set to 0.
