ViaRoutingTemplate(GHRequest ghRequest, GHResponse ghRsp, LocationIndex locationIndex, EncodedValueLookup lookup, Weighting weighting)

Method Summary

Modifier and Type	Method and Description
List<Path>	calcPaths(QueryGraph queryGraph, RoutingAlgorithmFactory algoFactory, AlgorithmOptions algoOpts) This method returns a list of Path objects which then can be merged to serve one route with via points or multiple alternative paths.
void	finish(PathMerger pathMerger, Translation tr) This method merges the returned paths appropriately e.g.
List<QueryResult>	lookup(List<GHPoint> points) This method takes the query points and returns the looked up QueryResults.

Method Detail

lookup

public List<QueryResult> lookup(List<GHPoint> points)

Description copied from interface: RoutingTemplate

Specified by:

lookup in interface RoutingTemplate

calcPaths

public List<Path> calcPaths(QueryGraph queryGraph,
                            RoutingAlgorithmFactory algoFactory,
                            AlgorithmOptions algoOpts)

Description copied from interface: RoutingTemplate

This method returns a list of Path objects which then can be merged to serve one route with via points or multiple alternative paths.

Specified by:

finish

public void finish(PathMerger pathMerger,
                   Translation tr)

Description copied from interface: RoutingTemplate

This method merges the returned paths appropriately e.g. all paths from the list into one ResponsePath of GHResponse or multiple (via / round trip).
