@ MultiLineString
MultiLineString.
Abstract base class for all geometries.
AxisOrder
Axis order for GML generation.
@ XY
X comes before Y (or lon before lat)
Qgis::WkbType wkbType() const
Returns the WKB type of the geometry.
virtual bool wktOmitChildType() const
Returns whether child type names are omitted from Wkt representations of the collection.
Line string geometry type, with support for z-dimension and m-values.
Multi curve geometry collection.
QString geometryType() const override
Returns a unique string representing the geometry type.
json asJsonObject(int precision=17) const override
Returns a json object representation of the geometry.
QgsMultiCurve * toCurveType() const override
Returns the geometry converted to the more generic curve type.
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 insertGeometry(QgsAbstractGeometry *g, int index) override
Inserts a geometry before a specified index and takes ownership.
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.
QgsMultiCurve * createEmptyWithSameType() const override
Creates a new geometry with the same class and same WKB type as the original and transfers ownership.
bool addGeometry(QgsAbstractGeometry *g) override
Adds a geometry and takes ownership. Returns true in case of success.
bool fromWkt(const QString &wkt) override
Sets the geometry from a WKT string.
QgsMultiCurve * clone() const override
Clones the geometry by performing a deep copy.
void clear() override
Clears the geometry, ie reset it to a null geometry.
Multi line string geometry collection.
static const QgsMultiLineString * cast(const QgsAbstractGeometry *geom)
Cast the geom to a QgsMultiLineString.
static Qgis::WkbType flatType(Qgis::WkbType type)
Returns the flat type for a WKB type.
