示例1: Relate

        public SpatialRelation Relate(Circle circle, SpatialContext ctx)
        {
            SpatialRelation bboxR = bbox.Relate(circle);
            if (bboxR == SpatialRelation.WITHIN || bboxR == SpatialRelation.DISJOINT)
                return bboxR;

            //Test each point to see how many of them are outside of the circle.
            //TODO consider instead using geom.apply(CoordinateSequenceFilter) -- maybe faster since avoids Coordinate[] allocation
            Coordinate[] coords = geom.Coordinates;
            int outside = 0;
            int i = 0;
            foreach (Coordinate coord in coords)
            {
                i++;
                SpatialRelation sect = circle.Relate(new PointImpl(coord.X, coord.Y, ctx));
                if (sect == SpatialRelation.DISJOINT)
                    outside++;
                if (i != outside && outside != 0)//short circuit: partially outside, partially inside
                    return SpatialRelation.INTERSECTS;
            }
            if (i == outside)
            {
                return (Relate(circle.GetCenter()) == SpatialRelation.DISJOINT)
                    ? SpatialRelation.DISJOINT : SpatialRelation.CONTAINS;
            }
            Debug.Assert(outside == 0);
            return SpatialRelation.WITHIN;
        }

示例2: RandomPointWithin

 private Point RandomPointWithin(Circle c)
 {
     double d = c.GetRadius() * random.NextDouble();
     double angleDEG = 360 * random.NextDouble();
     Point p = ctx.GetDistCalc().PointOnBearing(c.GetCenter(), d, angleDEG, ctx);
     Assert.Equal(SpatialRelation.CONTAINS, c.Relate(p, ctx));
     return p;
 }
