Constructor & Destructor Documentation

QgsGraphBuilder::QgsGraphBuilder	(	const QgsCoordinateReferenceSystem &	crs,
		bool	otfEnabled = `true`,
		double	topologyTolerance = `0.0`,
		const QString &	ellipsoidID = `"WGS84"`
	)

void QgsGraphBuilder::addArc	(	int	pt1id,
		const QgsPoint &	pt1,
		int	pt2id,
		const QgsPoint &	pt2,
		const QVector< QVariant > &	properties
	)

overridevirtual

add arc

Parameters

pt1id	first vertex identificator
pt1	first vertex coordinate
pt2id	second vertex identificator
pt2	second vertex coordinate
properties	arc properties

Note: pt1id, pt1 and pt2id, pt2 is a redundant interface. You can use vertex coordinates or their identificators.
