Subject [jira] Commented: (LUCENE-2915) make CoreCodecProvider convenience class so apps can easily pick per-field codecs
Date Thu, 10 Feb 2011 15:20:57 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-2915?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12993090#comment-12993090

Michael McCandless commented on LUCENE-2915:
--------------------------------------------

This sounds like a great idea!  (Automatically discovering external CPs contained in JARs
in the classpath).

If we can get that working, then I suppose we wouldn't need to hard-code our core codecs?
 Ie, they'd "naturally" be discovered since they are in the core JAR.

How would it work for codecs that take args to their ctor?  EG pulsing takes an int cutoff
(terms w/ <= that many positions are inlined into terms dict).

I think this should be a new issue?

> We already have DefaultCodecProvider, which simply registers all core codecs and uses
Standard for all fields, but it's package private.
> We should make this public, and name it CoreCodecProvider.
