Yonik Seeley commented on LUCENE-3795:
--------------------------------------
bq. Can I see the benchmark? The trivial things I am trying seems to end up
equivalent
One way that can happen is if you don't use the values produced - hotspot can
eliminate the method calls altogether.
{code}
public class X {
public static double foo(double val) {
// return Math.toRadians(val);
return val * (Math.PI/180.0);
}
public static void main(String[] args) {
double x = 1.12345;
for (int i=0; i<100000000; i++) {
x += foo(x) - foo(x+1);
}
System.out.println(x);
}
}
{code}
> Replace spatial contrib module with LSP's spatial-lucene module
> ---------------------------------------------------------------
>
> Key: LUCENE-3795
> URL: https://issues.apache.org/jira/browse/LUCENE-3795
> Project: Lucene - Java
> Issue Type: New Feature
> Components: modules/spatial
> Reporter: David Smiley
> Assignee: David Smiley
> Fix For: 4.0
>
>
> I propose that Lucene's spatial contrib module be replaced with the
> spatial-lucene module within Lucene Spatial Playground (LSP). LSP has been
> in development for approximately 1 year by David Smiley, Ryan McKinley, and
> Chris Male and we feel it is ready. LSP is here:
> http://code.google.com/p/lucene-spatial-playground/ and the spatial-lucene
> module is intuitively in svn/trunk/spatial-lucene/.
> I'll add more comments to prevent the issue description from being too long.
