inlinevirtual

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.

Reimplemented in QgsVectorLayerDirector.

◆ name()

virtual QString QgsGraphDirector::name ( ) const

pure virtual

Returns director name.
