Subject [jira] [Created] (LUCENE-4794) Refactor Spatial RecursivePrefixTreeFilter algorithm for extension
Date Thu, 21 Feb 2013 23:04:12 GMT
David Smiley created LUCENE-4794:

             Summary: Refactor Spatial RecursivePrefixTreeFilter algorithm for extension
                 Key: LUCENE-4794
             Project: Lucene - Core
          Issue Type: Improvement
          Components: modules/spatial
            Reporter: David Smiley
            Assignee: David Smiley
             Fix For: 4.2, 5.0

In the process of implementing algorithms on the SpatialPrefixTree indexed field like "Within"
or some variations of Intersects that say collect the distance as side-effect, I find that
I need near-copies of the code in RecursivePrefixTreeFilter.  RPTF is pretty intense with
lots of optimizations.  So I refactored out the algorithm such that it makes implementing
new algorithms much easier yet benefits from the logic in there.
