Michael McCandless updated LUCENE-4593:
---------------------------------------

    Attachment: LUCENE-4593.patch

Minor improvements, but an API change for the uber-Builder-ctor (the API is experimental): I changed allowArrayArcs from setter to ctor param (it doesn't make sense to change this while you are building).

Also added comment for lastFrozenNode ...

> I was looking at James patch for LUCENE-3298, and I thought that you know, FST *almost* abstracts its underlying "i/o" (storage) via reader/writer abstractions.
> It would be good to try to work on this more, e.g. we can imagine a little abstraction like lucene has a Store (Directory). 
> This way maybe we could cleanup the packed vs non-packed, allow for > 2GB fsts without slowing down small ones, and so on.
> I have a patch that is like an amoeba-step towards this
