static const QgsMultiPolygon * cast(const QgsAbstractGeometry *geom)
Cast the geom to a QgsMultiPolygon.
static QgsMultiPolygon * cast(QgsAbstractGeometry *geom)
Cast the geom to a QgsMultiPolygon.
QgsMultiPolygon()
Constructor for an empty multipolygon geometry.
QgsPolygon * polygonN(int index)
Returns the polygon with the specified index.
QgsMultiSurface()
Constructor for an empty multisurface geometry.

Adds a list of geometries to the collection, transferring ownership to the collection.
json asJsonObject(int precision=17) const override
Returns a json object representation of the geometry.
QgsMultiSurface * createEmptyWithSameType() const override
Creates a new geometry with the same class and same WKB type as the original and transfers ownership.

QgsMultiSurface * toCurveType() const override
Returns the geometry converted to the more generic curve type.
bool insertGeometry(QgsAbstractGeometry *g, int index) override
Inserts a geometry before a specified index and takes ownership.
void clear() override
