curveN

Returns the curve with the specified index.

fromCollectionWkt

Reads a collection from a WKT string.

fromWkt

param wkt

geometryType

rtype

str

hasChildGeometries

Returns whether the geometry has any child geometries (False for point / curve, True otherwise)

insertGeometry

param g

reversed

Returns a copy of the multi curve, where each component curve has had its line direction reversed.

setZMTypeFromSubGeometry

Updates the geometry type based on whether sub geometries contain z or m values.

sortIndex

Returns the sort index for the geometry, used in the compareTo() method to compare geometries of different types.

toCurveType

rtype

QgsMultiCurve

wktOmitChildType

Returns whether child type names are omitted from Wkt representations of the collection
