QgsMultiLineString
¶ Bases:
QgsMultiCurve
Multi line string geometry collection.
Methods
- param g
- param doc
- param doc
Returns point at index (for geometries without child geometries - i.e.
- rtype
QgsMultiLineString
- rtype
QgsMultiLineString
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
Updates the geometry type based on whether sub geometries contain z or m values.
Returns the geometry converted to the more generic curve type
