[jira] [Commented] (LUCENE-8566) Deprecate methods in CustomAnalyzer.Builder which take factory classes

    [ https://issues.apache.org/jira/browse/LUCENE-8566?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16876255#comment-16876255 ] 

Tomoko Uchida commented on LUCENE-8566:
---------------------------------------

I opened SOLR-13593 to allow to use SPI names in the Solr schema definition.

> CustomAnalyzer.Builder has methods which take implementation classes as follows.
>  - withTokenizer(Class<? extends TokenizerFactory> factory, String... params)
>  - withTokenizer(Class<? extends TokenizerFactory> factory, Map<String,String> params)
>  - addTokenFilter(Class<? extends TokenFilterFactory> factory, String... params)
>  - addTokenFilter(Class<? extends TokenFilterFactory> factory, Map<String,String> params)
>  - addCharFilter(Class<? extends CharFilterFactory> factory, String... params)
>  - addCharFilter(Class<? extends CharFilterFactory> factory, Map<String,String> params)
> Since the builder also has methods which take service names, it seems like that above methods are unnecessary and a little bit misleading. Giving symbolic names is preferable to implementation factory classes, but for now, users can write code depending on implementation classes.
> What do you think about deprecating those methods (adding {{@Deprecated}} annotations) and deleting them in the future releases? Those are called by only test cases so deleting them should have no impact on current lucene/solr codebase.
> If this proposal gains your consent, I will create a patch. (Let me know if I missed some point. I'll close it.)
