C++ (Cpp) Geometry::getNumGeometries示例

示例#1

文件： AbstractPreparedPolygonContains.cpp 项目： asapnet/geos

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);
