Michael McCandless resolved LUCENE-3177. ---------------------------------------- Resolution: Fixed > Decouple indexer from Document/Field impls > ------------------------------------------ > > Key: LUCENE-3177 > URL: https://issues.apache.org/jira/browse/LUCENE-3177 > Project: Lucene - Java > Issue Type: Improvement > Reporter: Michael McCandless > Assignee: Michael McCandless > Fix For: 4.0 > > Attachments: LUCENE-3177.patch, LUCENE-3177.patch > > > I think we should define minimal iterator interfaces, > IndexableDocument/Field, that indexer requires to index documents. > Indexer would consume only these bare minimum interfaces, not the > concrete Document/Field/FieldType classes from oal.document package. > Then, the Document/Field/FieldType hierarchy is one concrete impl of > these interfaces. Apps are free to make their own impls as well. > Maybe eventually we make another impl that enforces a global schema, > eg factored out of Solr's impl. > I think this frees design pressure on our Document/Field/FieldType > hierarchy, ie, these classes are free to become concrete > fully-featured "user-space" classes with all sorts of friendly sugar > APIs for adding/removing fields, getting/setting values, types, etc., > but they don't need substantial extensibility/hierarchy. Ie, the > extensibility point shifts to IndexableDocument/Field interface. > I think this means we can collapse the three classes we now have for a > Field (Fieldable/AbstracField/Field) down to a single concrete class > (well, except for LUCENE-2308 where we want to break out dedicated > classes for different field types...). -- This message is automatically generated by JIRA.
