twisted.python.zipstream : API documentation

Class	ChunkingZipFile	A `zipfile.ZipFile` object which, with `readfile`, also gives you access to a file-like object for each entry.
Class	ZipFileEntry	File-like object used to read an uncompressed entry in a ZipFile
Class	DeflatedZipFileEntry	File-like object used to read a deflated entry in a ZipFile
Function	countZipFileChunks	Predict the number of chunks that will be extracted from the entire zipfile, given chunksize blocks.
Function	countFileChunks	Count the number of chunks that will result from the given `ZipInfo`.
Function	unzipIterChunky	Return a generator for the zipfile. This implementation will yield after every chunksize uncompressed bytes, or at the end of a file, whichever comes first.
Class	_FileEntry	Abstract superclass of both compressed and uncompressed variants of file-like objects within a zip archive.

def countZipFileChunks(filename, chunksize): (source)

Predict the number of chunks that will be extracted from the entire zipfile, given chunksize blocks.

def countFileChunks(zipinfo, chunksize): (source)

Count the number of chunks that will result from the given ZipInfo.

Parameters	zipinfo	a `zipfile.ZipInfo` instance describing an entry in a zip archive to be counted.
Returns	the number of chunks present in the zip file. (Even an empty file counts as one chunk.) (type: `int`)

def unzipIterChunky(filename, directory='.', overwrite=0, chunksize=4096): (source)

Return a generator for the zipfile. This implementation will yield after every chunksize uncompressed bytes, or at the end of a file, whichever comes first.

The value it yields is the number of chunks left to unzip.
