Hello, fellow zope developers :)
I made a "nadako-sorting" branch of zope.index to add sorting support for zope indexes. I defined a new IIndexSort interface that specifies a "sort" method that takes document ids and returns an iterable of those ids, sorted by indexed value. It supports optional "limit" and "reverse" arguments. It also raises KeyError if you pass a docid that is not indexed by this index.
Can someone review the interface definition and make any suggestions/objections?
I also made an implementation for the FieldIndex that may not be too optimal, but I'm currently most interested in clean and universal IIndexSort definition that any index could efficiently implement.
If there's no objections, I'd like to merge it to trunk and start adding sorting features for zope.app.catalog/z3c.indexer, as well as zc.catalog indexes.
Thanks in advance!
Hi Dan, I've done this work too... but outside zope.index... please see (for example): http://svn.repoze.org/repoze.catalog/trunk/repoze/catalog/indexes/field.py It's reasonably optimized. - C
