Attachment: LUCENE-4634.patch
Here is a patch. (I would like to use it for LUCENE-4599.)
> PackedInts: streaming API that supports variable numbers of bits per value
> --------------------------------------------------------------------------

> It could be convenient to have a streaming API (writers and iterators, no
> random access) that supports variable numbers of bits per value. Although
> this would be much slower than the current fixed-size APIs, it could help
> save bytes in our codec formats.
> The API could look like:
> {code}
> Iterator {
> long next(int bitsPerValue);
> }
> Writer {
> void write(long value, int bitsPerValue); // assert
> PackedInts.bitsRequired(value) <= bitsPerValue;
> }
> {code}
