Class: QgsMultiLineString¶
- class qgis.core.QgsMultiLineString¶
Bases:
QgsMultiCurve
Multi line string geometry collection.
New in version 2.10.
QgsMultiLineString() Constructor for an empty multilinestring geometry.
QgsMultiLineString(
QgsMultiLineString
)Methods
- param g
- param doc
- param doc
Returns point at index (for geometries without child geometries - i.e. curve / point).
- 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
Returns the line string with the specified
index
.Updates the geometry type based on whether sub geometries contain z or m values.
Returns the sort index for the geometry, used in the
compareTo()
method to compare geometries of different types.Returns the geometry converted to the more generic curve type
