Member Function Documentation

void nlsr::RoutingTableCalculator::adjustAdMatrix ( int  source,
int  link,
double  linkCost 
)
protected

Adjust a link cost in the adj. matrix.

Parameters
sourceThe source router whose adjacency to adjust.
linkThe adjacency of the source to adjust.
linkCostThe cost to change to.

Here is the caller graph for this function:

void nlsr::RoutingTableCalculator::allocateLinks ( )
protected

Allocates an array large enough to hold multipath calculation temps.

Here is the caller graph for this function:

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

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

Parameters
sourceThe router whose values are to be adjusted.
linksAn integer pointer array for the link mappingNos.
linkCostsA 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 NON_ADJACENT_COST (-12345) 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

Parameters
sRouterThe router to count the links of.
