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.
int precision
QgsMultiCurve * toCurveType() const override
Returns the geometry converted to the more generic curve type.
const QgsMultiLineString * cast(const QgsAbstractGeometry *geom) const
Cast the geom to a QgsMultiLineString.
bool insertGeometry(QgsAbstractGeometry *g, int index) override
Inserts a geometry before a specified index and takes ownership.
Multi line string geometry collection.
virtual bool wktOmitChildType() const
Returns whether child type names are omitted from Wkt representations of the collection.
QString asJson(int precision=17) const override
Returns a GeoJSON representation of the geometry.
QgsMultiCurve * createEmptyWithSameType() const override
Creates a new geometry with the same class and same WKB type as the original and transfers ownership...
#define SIP_TRANSFER
Definition: qgis_sip.h:36
Multi curve geometry collection.
Definition: qgsmulticurve.h:29
#define SIP_FACTORY
Definition: qgis_sip.h:69
Abstract base class for all geometries.
QString geometryType() const override
Returns a unique string representing the geometry type.
QgsWkbTypes::Type wkbType() const
Returns the WKB type of the geometry.
bool fromWkt(const QString &wkt) override
Sets the geometry from a WKT string.
AxisOrder
Axis order for GML generation.
QgsMultiCurve * clone() const override
Clones the geometry by performing a deep copy.
bool addGeometry(QgsAbstractGeometry *g) override
Adds a geometry and takes ownership. Returns true in case of success.
void clear() override
Clears the geometry, ie reset it to a null geometry.
static Type flatType(Type type)
Returns the flat type for a WKB type.
Definition: qgswkbtypes.h:429
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.
