Nicolas Lalevée commented on LUCENE-778:
----------------------------------------
Rethinking about the function "public void document(int n, Document doc)", in
fact it will completely break the work I have done for LUCENE-662.
And finally, I agree with you Hoss. Two different interfaces, and let the user
implement the document he wants. As a first step, the user will decorate his
document. And in a second time, Lucene could provide the user the possibility
to have his own DocumentFactory.

> Key: LUCENE-778
> URL: https://issues.apache.org/jira/browse/LUCENE-778
> Project: Lucene - Java
> Issue Type: New Feature
> 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.
