Method Detail

getCost

public double getCost(boolean reverse)

Returns the cost of crossong the edge in the indicated direction.

Parameters:

reverse - is set to true if the traversal starts at the 'to' end of the edge and stops at the 'from' end, this can only happen if the edge is undirected.

getTime

public double getTime(boolean reverse)

Returns the time required to cross the edge in the indicated direction.

Parameters:

reverse - is set to true if the traversal starts at the 'to' end of the edge and stops at the 'from' end, this can only happen if the edge is undirected.

getDistance

public double getDistance(boolean reverse)

Returns the distance across the edge in the indicated direction.

Parameters:

reverse - is set to true if the traversal starts at the 'to' end of the edge and stops at the 'from' end, this can only happen if the edge is undirected.
