Examples of org.geotools.geometry.jts.CircularRing

org.geotools.geometry.jts.CircularRing
A CircularRing is a CircularString whose start and end point coincide. The ring needs to be formed of at least two arc circles, in order to be able to determine its orientation. @author Andrea Aime - GeoSolutions

        Polygon p = (Polygon) g;
        assertEquals(0, p.getNumInteriorRing());


        // exterior ring checks
        assertTrue(p.getExteriorRing() instanceof CircularRing);
        CircularRing shell = (CircularRing) p.getExteriorRing();
        assertTrue(CurvedGeometries.isCircle(shell));
        CircularArc arc = shell.getArcN(0);
        assertEquals(5, arc.getRadius(), 0d);
        assertEquals(new Coordinate(15, 150), arc.getCenter());
