AbstractRegion throws NullPointerException exception
gün alppay created MATH-1162:
--------------------------------
Summary: contains(Region<S> region) method of AbstractRegion throws NullPointerException exception
Key: MATH-1162
URL: https://issues.apache.org/jira/browse/MATH-1162
Project: Commons Math
Issue Type: Bug
Affects Versions: 3.3
Environment: tested on windows 8 and heroku
Reporter: gün alppay
the contains call on org.apache.commons.math3.geometry.partitioning.AbstractRegion throws an exception in the sample below:
import org.apache.commons.math3.geometry.partitioning.Region;
import org.apache.commons.math3.geometry.euclidean.twod.Vector2D;
import org.apache.commons.math3.geometry.euclidean.twod.Euclidean2D;
import org.apache.commons.math3.geometry.euclidean.twod.PolygonsSet;
class Test {
public static void main(String[] args) {
Region<Euclidean2D> p = new PolygonsSet( 1.0e-10,
new Vector2D(4.267199999996532, -11.928637756014894),
new Vector2D(4.267200000026445, -14.12360595809307),
new Vector2D(9.144000000273694, -14.12360595809307),
new Vector2D(9.144000000233383, -11.928637756020067));
Region<Euclidean2D> w = new PolygonsSet( 1.0e-10,
new Vector2D(2.56735636510452512E-9, -11.933116461089332),
new Vector2D(2.56735636510452512E-9, -12.393225665247766),
new Vector2D(2.56735636510452512E-9, -27.785625665247778),
new Vector2D(4.267200000030211, -27.785625665247778),
new Vector2D(4.267200000030211, -11.933116461089332));
p.contains(w);
}
}
the exception thrown is:
