Method Details

init(self, pair_iter)
(Constructor)

Construct a TarFromIterator instance. pair_iter is an iterator of (TarInfo, fileobj) objects, which fileobj should be a file-like object opened for reading, or None. The fileobjs will be closed before the next element in the iterator is read.

Overrides: TarFile.__init__

seek(self, offset)

Seek to current position. Just read and discard some amount

_addtobuffer(self)

Write more data into the buffer. Return None if at end

close(self)

Close file obj

Overrides: TarFile.close
