Uwe Schindler commented on LUCENE-1701:
---------------------------------------
bq. Could you add the "<b>NOTE:</b> This API is experimental and might change
in incompatible ways in the next release." caveat to the javadocs?
For the whole TrieAPI or only NumericUtils? If the first, I would do this with
an general JavaDoc commit after this issue. If only NumericField, I could do it
now.
bq. Can you change this:
Sure, we had this the last time, too (I like my variant more, so I always
automatically write it in that way)
bq. I think we can't actually deprecate NumberTools until we can call
FieldCache.getShorts/getBytes on a NumericField? Ie, people relying on
short/byte (to consume much less memory in FieldCache) cannot switch to
numeric, and so must continue to zero-pad if they need to use RangeQuery/Filter?
I will open an issue because of this byte/short trie fields.
NumberTools does not handle zero-padding, so it could stay deprecated. Numbers
encoded with NumberTools cannot be natively sorted on at all (only using
StringIndex) and can only handle longs.
You may mean NumberUtils from Solr in contrib/spatial, but this class is not
yet released and is only used for spatial.
bq. You need a CHANGES entry.
Will come.

> In discussions about LUCENE-1673, Mike & me wanted to add a new NumericField
> to o.a.l.document specific for easy indexing. An alternative would be to add
> a NumericUtils.newXxxField() factory, that creates a preconfigured Field
> instance with norms and tf off, optionally a stored text (LUCENE-1699) and
> the TokenStream already initialized. On the other hand
> NumericUtils.newXxxSortField could be moved to NumericSortField.
> I and Yonik tend to use the factory for both, Mike tends to create the new
> classes.
> Also the parsers for string-formatted numerics are not public in FieldCache.
> As the new SortField API (LUCENE-1478) makes it possible to support a parser
> in SortField instantiation, it would be good to have the static parsers in
> FieldCache public available. SortField would init its member variable to them
> (instead of NULL), so making code a lot easier (FieldComparator has this ugly
> null checks when retrieving values from the cache).
> Moving the Trie parsers also as static instances into FieldCache would make
> the code cleaner and we would be able to hide the "hack"
> StopFillCacheException by making it private to FieldCache (currently its
> public because NumericUtils is in o.a.l.util).
