WkbType
The WKB type describes the number of dimensions a geometry has.
Definition qgis.h:256
@ MultiPolygon
MultiPolygon.
@ MultiSurface
MultiSurface.
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.
QgsGeometryCollection * toCurveType() const override
Returns the geometry converted to the more generic curve type.
json asJsonObject(int precision=17) const override
Returns a json object representation of the geometry.
bool fromWkt(const QString &wkt) override
Sets the geometry from a WKT string.
void clear() override
Clears the geometry, ie reset it to a null geometry.
QString geometryType() const override
Returns a unique string representing the geometry type.
virtual bool insertGeometry(QgsAbstractGeometry *g, int index)
Inserts a geometry before a specified index and takes ownership.
virtual QgsGeometryCollection * simplifyByDistance(double tolerance) const override
Simplifies the geometry by applying the Douglas Peucker simplification by distance algorithm.
QgsAbstractGeometry * boundary() const override
Returns the closure of the combinatorial boundary of the geometry (ie the topological boundary of the...
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.
QgsGeometryCollection * clone() const override
Clones the geometry by performing a deep copy.
virtual bool addGeometries(const QVector< QgsAbstractGeometry * > &geometries)
Adds a list of geometries to the collection, transferring ownership to the collection.
QgsGeometryCollection * createEmptyWithSameType() const override
Creates a new geometry with the same class and same WKB type as the original and transfers ownership.
virtual bool addGeometry(QgsAbstractGeometry *g)
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.
Multi surface geometry collection.
static const QgsMultiSurface * cast(const QgsAbstractGeometry *geom)
Cast the geom to a QgsMultiSurface.
Surface geometry type.
Definition qgssurface.h:34
static Qgis::WkbType flatType(Qgis::WkbType type)
Returns the flat type for a WKB type.
