Simon Willnauer commented on LUCENE-2081:
-----------------------------------------
IMO we should start a refactoring beginning with Shape and
CartesianPolyFilterBuilder.
This needs Documentation, cleanup and optimization. The Shape List<Double>
member bugs me in particular - we could save a lot of object creations when we
could change this to an array of doubles where Shapes and their arrays could be
reused somehow.
I have reserved some time to work on spatial in Dec. CartesianPolyFilterBuilder
is the place to start from my point of view.
> CartesianShapeFilter improvements

> Key: LUCENE-2081
> URL: https://issues.apache.org/jira/browse/LUCENE-2081
> Project: Lucene - Java
> Issue Type: Improvement
> Components: contrib/spatial
> Affects Versions: 2.9
> Reporter: Grant Ingersoll
> Priority: Minor
>
> The CartesiahShapeFilter could use some improvements. For starters, if we
> make sure the boxIds are sorted in index order, this should reduce the cost
> of seeks. I think we should also replace the logging with a similar approach
> to Lucene's output stream. We also can do Term creation a tad bit more
> efficiently too.
