Abstract base class for all geometries.
AxisOrder
Axis order for GML generation.
QgsWkbTypes::Type wkbType() const SIP_HOLDGIL
Returns the WKB type of the geometry.
virtual bool wktOmitChildType() const
Returns whether child type names are omitted from Wkt representations of the collection.
Multi polygon geometry collection.
static const QgsMultiPolygon * cast(const QgsAbstractGeometry *geom)
Cast the geom to a QgsMultiPolygonV2.
Multi surface geometry collection.
QDomElement asGml2(QDomDocument &doc, int precision=17, const QString &ns="gml", QgsAbstractGeometry::AxisOrder axisOrder=QgsAbstractGeometry::AxisOrder::XY) const override
Returns a GML2 representation of the geometry.
bool addGeometry(QgsAbstractGeometry *g) override
Adds a geometry and takes ownership. Returns true in case of success.
QDomElement asGml3(QDomDocument &doc, int precision=17, const QString &ns="gml", QgsAbstractGeometry::AxisOrder axisOrder=QgsAbstractGeometry::AxisOrder::XY) const override
Returns a GML3 representation of the geometry.
bool fromWkt(const QString &wkt) override
Sets the geometry from a WKT string.
QgsMultiSurface * clone() const override
Clones the geometry by performing a deep copy.
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.
QgsAbstractGeometry * boundary() const override
Returns the closure of the combinatorial boundary of the geometry (ie the topological boundary of the...
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
Clears the geometry, ie reset it to a null geometry.
QString geometryType() const override SIP_HOLDGIL
Returns a unique string representing the geometry type.
Polygon geometry type.
Definition: qgspolygon.h:34
