Class com.vividsolutions.jts.geom.Geometry

Examples of com.vividsolutions.jts.geom.Geometry.apply()

com.vividsolutions.jts.geom.Geometry.apply()
Performs an operation with or on this Geometry's coordinates. If this method modifies any coordinate values, {@link #geometryChanged} must be called to update the geometry state. Note that you cannot use this method to modify this Geometry if its underlying CoordinateSequence's #get method returns a copy of the Coordinate, rather than the actual Coordinate stored (if it even stores Coordinate objects at all). @param filter the filter to apply to this Geometry'scoordinates

                Geometry intersection = aFilter.intersection(bFilter);
                if (intersection instanceof MultiPolygon) {
                    rasterFilter = (MultiPolygon)intersection;
                } else {
                    final List<Polygon> accum = new ArrayList<Polygon>();
                    intersection.apply(
                        new GeometryComponentFilter() {
                            public void filter(Geometry geom) {
                                if (geom instanceof Polygon) accum.add((Polygon)geom);
                            }
                        }
