Re: Indexing

Hi Peter,
just declare dedicated members in your RootObject ( or in other data object
).

If you make your reads through the Queries, HashMaps are ok. If you read
RootObject directly, use ConcurrentHashMap ( and remember to synchronize in
your reads and writes ).


simplified example:

class RootObject {
...
   private Map<Long, Book> bookIndex = new HashMap<Long, Book>();
...
   Long addBook( Book book ) {
       Long newId = generateNextBookId();
       book.setId( newId );
       bookIndex.put( newId, book);
   }
...
}

P.S. And please send/ publish you results when you have them.
