[ https://issues.apache.org/jira/browse/LUCENE-2389?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Uwe Schindler updated LUCENE-2389:
----------------------------------
Fix Version/s: 3.1
> Enforce TokenStream impl / Analyzer finalness by an assertion
> -------------------------------------------------------------
>
> Key: LUCENE-2389
> URL: https://issues.apache.org/jira/browse/LUCENE-2389
> Project: Lucene - Java
> Issue Type: Improvement
> Reporter: Uwe Schindler
> Assignee: Uwe Schindler
> Fix For: 3.1
>
>
> As noted in LUCENE-1753 and other issues, TokenStream and Analyzers are based on the decorator pattern. At least all TokenStream and Analyzer implementations in Lucene and Solr should be final.
> The attached patch adds an assertion to the ctors of both classes that does the corresponding checks:
> - Analyzers must be final or private classes or anonymous inner classes
> - TokenStreams must be final or private classes or anonymous inner classes or have a final incrementToken()
> I will commit this after robert have fixed solr streams.
