makeGraph(self, builder: QgsGraphBuilderInterface, additionalPoints: Iterable[QgsPointXY], feedback: QgsFeedback = None) → List[QgsPointXY]

Make a graph using QgsGraphBuilder

Parameters:

• builder – the graph builder
• additionalPoints – list of points that should be snapped to the graph
• snappedPoints – list of snapped points
• feedback – feedback object for reporting progress

Note

if snappedPoints[i] == QgsPointXY(0.0,0.0) then snapping failed.

name(self) → str

Returns director name
