Review Comment: > it seems to me that allowing would make the api contract simple(but at the cost of doing unneccessary work)....Is that correct? This is correct! I agree with your sentiment, I got there because I wanted to avoid some performance traps, but it has gone too far, the API contract is too complex. I pushed a change so that it's legal to call the methods in any order, it just happens to be a bit more efficient to call bits() before iterator() than iterator() before bits(). -- This is an automated message from the Apache Git Service.
