Simon Willnauer commented on LUCENE-3862:
-----------------------------------------
I should have been more specific. The reason why I did it that way is that you
always have to explicitly downcast if you are sure you are not loosing any
precision. If you offer a getShort somebody could accidentally downcast its 64
bit values into a 16 bit values without realizing. However, if it allows us to
make similarities generic we need to rething that maybe.
I kind of like the semantics we have right now ie. you get full 64 bit values
no matter what you have encoded.
