Subject [jira] [Commented] (LUCENE-4317) Field.java does not reuse its inlined Keyword-TokenStream
Date Tue, 21 Aug 2012 09:22:38 GMT

Chris Male commented on LUCENE-4317:
------------------------------------

Thanks for tackling this Uwe.  

bq. We should maybe think about a solution how to "cache" the instances across several instances
(like IndexWriter did in 3.x)

Do you mean also for NumericTokenStream? or just StringTokenStream?

> Field.java contains a inlined Keyword-TokenStream. Unfortunately this one is recreated
all the time, although one reuses the same Field instance. For NumericTokenStream Field.java
reuses it, but the Keyword one not.
> We should apply the same logic and lazy init the TokenStream with a setter for the String
value and reset(). This would be looking identical to SetNumeric(xx).
