Sounds great, and be sure to express any difficulties/shortcomings with the API so that it can improved for these kinds of scenarios. It may be that you have to make the constructor public (I don't know in what way the service API uses reflection and all that). Also there's this assumption that an IndexProvider provides its own data source. The spatial index provider uses the graph itself (right?) so it could be a problem. Let me look at and fix that, and then document how that's done for such a scenario (hopefully tomorrow). > > Cheers, > > /peter neubauer > > GTalk: neubauer.peter > Skype peter.neubauer > Phone +46 704 106975 > LinkedIn http://www.linkedin.com/in/neubauer > Twitter http://twitter.com/peterneubauer > > http://www.neo4j.org - Your high performance graph database. > http://www.thoughtmade.com - Scandinavia's coolest Bring-a-Thing party. > _______________________________________________ > Neo4j mailing list > User@lists.neo4j.org > https://lists.neo4j.org/mailman/listinfo/user > -- Mattias Persson, [matt...@neotechnology.com] Hacker, Neo Technology www.neotechnology.com _______________________________________________ Neo4j mailing list User@lists.neo4j.org https://lists.neo4j.org/mailman/listinfo/user
