Class PagingDecoder

x.__init__(...) initializes x; see x.__class__.__doc__ for signature

Overrides: object.__init__

(inherited documentation)

Takes an iterator of bytes, returns an iterator of iterators of uncompressed data. Expects input to conform to the output conventions of PagingEncoder(), in particular that "pages" are separated with an END_OF_INFO_CODE and padding up to the next byte boundary.

BUG: Dangling trailing page on decompression.
