Detailed Description

Determine interface for creating a graph.

Contains the settings of the graph. QgsGraphBuilder and QgsGraphDirector is a Builder pattern

Definition at line 34 of file qgsgraphbuilderintr.h.

Constructor & Destructor Documentation

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

inline

QgsGraphBuilderInterface constructor.

Parameters

crs	Coordinate reference system for new graph vertex
ctfEnabled	enable coordinate transform from source graph CRS to CRS graph
topologyTolerance	sqrt distance between source point as one graph vertex
ellipsoidID	ellipsoid for edge measurement

virtual QgsGraphBuilderInterface::~QgsGraphBuilderInterface ( )

inlinevirtual

Destructor.

Member Function Documentation

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

inlinevirtual

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 in QgsGraphBuilder.

Definition at line 101 of file qgsgraphbuilderintr.h.

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

inlinevirtual

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
