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

Member Function Documentation

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

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.

Reimplemented from QgsGraphBuilderInterface.

void QgsGraphBuilder::addVertex	(	int	id,
		const QgsPoint &	pt
	)		[virtual]

add vertex

Parameters:

id	vertex identifier
pt	vertex coordinate

Note:

id and pt are redundant. You can use pt or id to identify the vertex
