Member Function Documentation

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

Make a graph using RgGraphBuilder.

builderThe graph builder
additionalPointsVector of points that must be tied to the graph
tiedPointsVector of tied points
if tiedPoints[i]==QgsPoint(0.0,0.0) then tied failed.
