示例1: return
bool
AbstractPreparedPolygonContains::isSingleShell( const geom::Geometry & geom)
{
// handles single-element MultiPolygons, as well as Polygons
if ( geom.getNumGeometries() != 1)
return false;
const geom::Polygon * poly = (Polygon *)geom.getGeometryN( 0);
int numHoles = poly->getNumInteriorRing();
return (numHoles == 0);
}示例2:
