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.
int	getMaxRetries() This method returns the maximum number of full retries of these 3 steps
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

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

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

calcPaths

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.

isReady

boolean isReady(PathMerger pathMerger,
                Translation tr)

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

getMaxRetries

int getMaxRetries()

This method returns the maximum number of full retries of these 3 steps
