Detailed Description

The GKSPManager holds all the shortest paths in a network. It calculates the shortest path using the cost of each object (section and turn). The cost can be:

• Distance: Length of the object.
• Time: Time needed to cross the object using the length and speed of the section.
• Attribute: One of one attribute of the object.
• Function: Not yet implemented.

The user of this class must first create an instance, then assign the cost type to be used, then the time context (if selected and attribute with Time Series as they depends of the time), then the attribute (if the type was Attribute). After setting the class call the build function. Then calls to the class can be done to get the shortest path between two sections.

Member Function Documentation

build() [1/2]

void GKSPManager::build	(	GKModel *	,
		const GKGenericExperiment *	filterExperiment
	)

Calculates the shortest paths.

build() [2/2]

void GKSPManager::build	(	GKModel *	model,
		const GKGenericExperiment *	filterExperiment,
		const QVector< GKVehicleClass * > &	vClas,
		GKVehicle *	vehicle = nullptr
	)

Calculates the shortest paths taking into account only sections in where "vehicle" can circulated.

calculate()

float GKSPManager::calculate	(	GKBezierCurve *	from,
		GKBezierCurve *	to,
		QString &	eventStr
	)		const

Calculates the cost of the path beetwen two sections. If no path is found it returns a -1.

cost()

float GKSPManager::cost	(	GKSection *	from,
		GKSection *	to
	)		const

returns the actual cost of the path beetwen two sections. If no path is found it returns a -1.

getPath() [1/2]

QVector< GKSection * > GKSPManager::getPath	(	GKCentroid *	,
		GKCentroid *
	)

Get the Path between two centroids. If no path is found an empty vector will be returned.

getPath() [2/2]

QVector< GKSection * > GKSPManager::getPath	(	GKSection *	,
		GKSection *
	)

Get the Path between two sections. If no path is found an empty vector will be returned.

setAttributeCost()

void GKSPManager::setAttributeCost	(	GKColumn *	,
		GKColumn *
	)

For eAttribute cost type set the attributes to use for sections and turns.

setContext()

void GKSPManager::setContext

(

const GKContext &

)

Set the time context (the Now) when using Time Series.

setCostType()

void GKSPManager::setCostType

(

const

GKSPManagerCostType

)

Set the type of the cost. This function must be call before function "build".
