Nicolas Lalevée commented on LUCENE-778:
----------------------------------------
Just after committing the jira issue, I just figured out that I haven't
searched for topics about it. Sorry.
BTW, thanks for the pointers.
But what my request here is not making Lucene providing customized documents,
like in LUCENE-662, it is about allowing passing to writer.addDocument() a
document that is extending Document, nothing more.
For instance, I would like to do something like that :
public RDFDocument extends Document {
public RDFDocument(String uri) {
add(new Field("uri", uri);
}
public void addStatement(String prop, String value) {
add(new Field(prop, value));
}
}
Should we move this discussion to lucene-dev ?
> Allow overriding a Document
> ---------------------------
>
> 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.
