------------------------------------
Summary: Refactor Spatial RecursivePrefixTreeFilter algorithm for
extension
Key: LUCENE-4794
URL: https://issues.apache.org/jira/browse/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.
Patch to follow...
