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.
boolean	isReady(PathMerger pathMerger, Translation tr) This method merges the returned paths appropriately e.g.
List<QueryResult>	lookup(List<GHPoint> points, FlagEncoder encoder) This method takes the query points and returns the looked up QueryResults.

Method Detail

lookup

public List<QueryResult> lookup(List<GHPoint> points,
                                FlagEncoder encoder)

Description copied from interface: RoutingTemplate

This method takes the query points and returns the looked up QueryResults.

Specified by:

lookup in interface RoutingTemplate

Overrides:

lookup in class ViaRoutingTemplate

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:

calcPaths in interface RoutingTemplate

Overrides:

isReady

public boolean isReady(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 PathWrapper of GHResponse or multiple (via / round trip).

Specified by:
