addEdges

public void addEdges(Collection<EdgeIteratorState> edges)

This method adds the specified path to this weighting which should be penalized in the calcWeight method.

calcEdgeWeight

public double calcEdgeWeight(EdgeIteratorState edgeState,
                             boolean reverse)

Description copied from interface: Weighting

This method calculates the weight of a given EdgeIteratorState. E.g. a high value indicates that the edge should be avoided during shortest path search. Make sure that this method is very fast and optimized as this is called potentially millions of times for one route or a lot more for nearly any preprocessing phase.

Specified by:

calcEdgeWeight in interface Weighting

Overrides:

calcEdgeWeight in class AbstractAdjustedWeighting

Parameters:

edgeState - the edge for which the weight should be calculated

reverse - if the specified edge is specified in reverse direction e.g. from the reverse case of a bidirectional search.

Returns:

the calculated weight with the specified velocity has to be in the range of 0 and +Infinity. Make sure your method does not return NaN which can e.g. occur for 0/0.
