Constructor & Destructor Documentation

QgsLineVectorLayerDirector::QgsLineVectorLayerDirector	(	QgsVectorLayer *	myLayer,
		int	directionFieldId,
		const QString &	directDirectionValue,
		const QString &	reverseDirectionValue,
		const QString &	bothDirectionValue,
		int	defaultDirection
	)

Parameters:

myLayer	source vector layer
directionFieldId	feield contain road direction value
directDirectionValue	value for one-way road
reverseDirectionValue	value for reverse one-way road
bothDirectionValue	value for road
defaultDirection	1 - direct direction, 2 - reverse direction, 3 - both direction

Member Function Documentation

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

Make a graph using RgGraphBuilder.

Parameters:

builder	The graph builder
additionalPoints	Vector of points that must be tied to the graph
tiedPoints	Vector of tied points

Note:

if tiedPoints[i]==QgsPoint(0.0,0.0) then tied failed.

Reimplemented from QgsGraphDirector.
