[jira] Updated: (LUCENE-2788) Make CharFilter reusable

["Robert Muir (JIRA)" <ji...@apache.org>]

Robert Muir updated LUCENE-2788:
--------------------------------

    Attachment: LUCENE-2788.patch

here's a very quick patch (all tests pass):
* Changed CharFilter to extend FilterReader, and removed CharStream and CharReader.
* added reset(Reader) to CharFilter, so you can reset your entire charfilter chain with a new reader.
* changed Solr to re-use the charfilter chain in its Analyzers.

it would be nice to add specific reuse tests to some of these charfilters, and also to see
if theres a way we can do this with any backwards compatibility... i didnt worry about that when making the patch.

> The CharFilter API lets you wrap a Reader, altering the contents before the Tokenizer sees them.
> It also allows you to correct the offsets so this is transparent to highlighting.
> One problem is that the API isn't reusable, if you have a lot of short documents its going to be efficient.
> Additionally there is some unnecessary wrapping in Tokenizer (see the CharReader.get in the ctor, but *not* in reset(Reader)!!!)
