So the API will look like : class IndexReader { ReturnableDocument doc(int n); } class IndexWriter { void addDocument(IndexableDocument doc); } 1) it does matter from the user point of view : we cannot do anymore writer= .addDocument(reader.doc(10)). 2) Effectively I can implement a DecoratedDocument. But I cannot make Lucen= e instanciating my own document, the reader will still return some Returnab= leDocument. Unless you want to allow the user to customize in Lucene the in= stanciation of Document by providing a factory of Document ? > 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 Lalev=C3=A9e > 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 w= ith 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 ap= plication, ie some MyAppDocument and MyOtherAppDocument which have a proper= ty holding a real Lucene Document. Then, when MyApp or MyOtherApp want to u= se our generic lucene API, we have to "get out" the Lucene document, ie do = some genericLuceneAPI.writeDoc(myAppDoc.getLuceneDocument()). This work fin= e, but it becomes quite tricky to use the other function of our generic API= which is genericLuceneAPI.writeDocs(Collection docs). > I don't know the rational behind making final Document, but removing it w= ill allow more object-oriented code. --=20 This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online. --------------------------------------------------------------------- To unsubscribe, e-mail: java-dev-unsubscribe@lucene.apache.org For additional commands, e-mail: java-dev-help@lucene.apache.org
