copyInternal method
An internal method to copy subclass-specific geometry data.
@return a copy of the target geometry object.
Implementation
MultiPolygon copyInternal() {
List<Polygon> polygons = []; //..length = this.geometries.length;
for (int i = 0; i < this.geometries.length; i++) {
polygons.add(this.geometries[i].copy() as Polygon);
}
return new MultiPolygon.withFactory(polygons, geomFactory);
}
