Example 1 with Circle

use of org.locationtech.spatial4j.shape.Circle in project lucene-solr by apache.

the class TestPointVectorStrategy method testCircleShapeSupport.

@Test
public void testCircleShapeSupport() {
    this.strategy = PointVectorStrategy.newInstance(ctx, getClass().getSimpleName());
    Circle circle = ctx.makeCircle(ctx.makePoint(0, 0), 10);

Example 2 with Circle

use of org.locationtech.spatial4j.shape.Circle in project lucene-solr by apache.

the class HeatmapFacetCounterTest method testQueryCircle.

@Test
