Class QueryRoutingCHGraph

java.lang.Object

com.graphhopper.routing.querygraph.QueryRoutingCHGraph

All Implemented Interfaces:

RoutingCHGraph

public class QueryRoutingCHGraph
extends Object
implements RoutingCHGraph

This class is used to allow routing between virtual nodes (snapped coordinates that lie between the nodes of the original graph) when using CH. To use it first create a QueryGraph just as if you were not using CH and then create an instance of the present class on top of this.

getEdgeIteratorState

public RoutingCHEdgeIteratorState getEdgeIteratorState(int chEdge,
                                                       int adjNode)

Specified by:

getBaseGraph in interface RoutingCHGraph

Returns:

the graph this CH graph is based on, i.e. a the base Graph or a QueryGraph on top of the base graph todo: maybe it would be better to remove this method and use a direct reference to the base graph when it is needed
