Member Function Documentation

void QgsLineVectorLayerDirector::makeGraph ( QgsGraphBuilderInterface *  builder, const QVector< QgsPoint > &  additionalPoints, QVector< QgsPoint > &  tiedPoints  ) const

overridevirtual

Make a graph using RgGraphBuilder.

Parameters

builder	The graph builder
additionalPoints	Vector of points that must be tied to the graph
tiedPoints	Vector of tied points

Note

if tiedPoints[i]==QgsPoint(0.0,0.0) then tied failed.

Reimplemented from QgsGraphDirector.
