Detailed Description

This class making the QgsGraph object.

Constructor & Destructor Documentation

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

default constructor

QgsGraphBuilder::~QgsGraphBuilder ( )

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.

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

virtual

add vertex

Parameters

id	vertex identifier
pt	vertex coordinate

QgsGraph * QgsGraphBuilder::graph ( )

return QgsGraph result;
