[jira] [Resolved] (LUCENE-778) Allow overriding a Document
[ https://issues.apache.org/jira/browse/LUCENE-778?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Erick Erickson resolved LUCENE-778.
-----------------------------------
Resolution: Won't Fix
SPRING_CLEANING_2013 We can reopen if necessary. Think this code has been extensively re-worked anyway.

> Key: LUCENE-778
> URL: https://issues.apache.org/jira/browse/LUCENE-778
> Project: Lucene - Core
> Issue Type: New Feature
> Components: core/index
> Affects Versions: 2.0.0
> Reporter: Nicolas Lalevée
> Priority: Trivial
>
> In our application, we have some kind of generic API that is handling how we are using Lucene. The different other applications are using this API with different semantics, and are using the Lucene fields quite differently. We wrote some usefull functions to do this mapping. Today, as the Document class cannot be overriden, we are obliged to make a document wrapper by application, ie some MyAppDocument and MyOtherAppDocument which have a property holding a real Lucene Document. Then, when MyApp or MyOtherApp want to use our generic lucene API, we have to "get out" the Lucene document, ie do some genericLuceneAPI.writeDoc(myAppDoc.getLuceneDocument()). This work fine, but it becomes quite tricky to use the other function of our generic API which is genericLuceneAPI.writeDocs(Collection<Document> docs).
> I don't know the rational behind making final Document, but removing it will allow more object-oriented code.
