QgsMultiCurve
¶ Bases:
QgsGeometryCollection
Multi curve geometry collection.
Methods
- param g
- param doc
- param doc
- rtype
QgsAbstractGeometry
Returns point at index (for geometries without child geometries - i.e.
- rtype
QgsMultiCurve
- rtype
QgsMultiCurve
Reads a collection from a WKT string.
- param wkt
- rtype
str
Returns whether the geometry has any child geometries (
False
for point / curve,True
otherwise)- param g
Returns a copy of the multi curve, where each component curve has had its line direction reversed.
Updates the geometry type based on whether sub geometries contain z or m values.
- rtype
QgsMultiCurve
Returns whether child type names are omitted from Wkt representations of the collection
