Parameters

source	The source router whose adjacency to adjust.
link	The adjacency of the source to adjust.
linkCost	The cost to change to.

void nlsr::RoutingTableCalculator::getLinksFromAdjMatrix	(	int *	links,
		double *	linkCosts,
		int	source
	)

protected

Populates temp. variables with the link costs for some router.

Parameters

source	The router whose values are to be adjusted.
links	An integer pointer array for the link mappingNos.
linkCosts	A double pointer array that stores the link costs.

Obtains a sparse list of adjacencies and link costs for some router. Since this is sparse, that means while generating these arrays, if there is no adjacency at i in the matrix, these temporary variables will not contain a 0 at i, but rather will contain the values for the next valid adjacency.

Here is the caller graph for this function:

int nlsr::RoutingTableCalculator::getNumOfLinkfromAdjMatrix ( int sRouter )

protected

Returns how many links a router in the matrix has.

Parameters

sRouter The router to count the links of.

Here is the caller graph for this function:

void nlsr::RoutingTableCalculator::initMatrix ( )

protected

Zero every cell of the matrix to ensure that the memory is safe.
