Detailed Description

The class storing the generated network.

An instance of this class stores both the edges and the nodes build during the generation of a network (using any type of generation algorithm). These instances are later transformed into netbuild-structures using toNB().

void NGNet::createChequerBoard	(	int	numX,
		int	numY,
		double	spaceX,
		double	spaceY,
		double	xAttachLength,
		double	yAttachLength
	)

Creates a grid network.

Performs a double-loop over numX, then numY. Builds NGNodes at the according positions and connects them using NGNet::connect. Stores both the nodes and the edges within the internal container.

The nodes get an id using <RUNNING_X>/<RUNNING_Y>. The ids of the links are set in NGNet::connect.

Parameters

[in]	numX	The number of nodes in x-direction
[in]	numY	The number of nodes in y-direction
[in]	spaceX	The space between nodes in x-direction
[in]	spaceY	The space between nodes in y-direction
[in]	xAttachLength	The length of streets attached at the border in x-direction
[in]	yAttachLength	The length of streets attached at the border in y-direction

◆ createSpiderWeb()

void NGNet::createSpiderWeb	(	int	numRadDiv,
		int	numCircles,
		double	spaceRad,
		bool	hasCenter,
		double	attachLength
	)

Creates a spider network.

Creates a spider web by going through all arms and then all circles in a loop. Builds the NGNodes at the positions obtained using radialToX and radialToY and connects them using NGNet::connect. Builds optionally a center node, and connects it, too.

The nodes get an id using <RUNNING_ARM_NUMBER>/<RUNNING_CIRCLE_NUMBER>. The ids of the links are set in NGNet::connect.

Parameters

[in]	numRadDiv	The number of arms to build
[in]	numCircles	The number of circles to build
[in]	spaceRad	The distance between the circles
[in]	hasCenter	Information whether a center node shall be built

◆ toNB()

void NGNet::toNB ( ) const

Converts the stored network into its netbuilder-representation.

Goes through all stored nodes, first, converts them into their netbuilder representations using NGNode::buildNBNode, and stores the built NBNodes into the net builder myNetBuilder.

Then, the method goes through all edges, converts them into their netbuilder representations using NGEdge::buildNBEdge, and stores the built NBEdges into the net builder myNetBuilder.

If one of the nodes is controlled by a tls and the built logic could not be added to net builder's storage, a ProcessError is thrown. This in fact may only happen when two same ids occur, what is not possible.

Exceptions

ProcessError If a built tls logic could not be added (should never happen)

Todo:: Check whether throwing an exception is really necessary, here
