Graphs(OptimizedMapLayers optimizedMap)	Creates a Graphs from an Optimized Map for Location Library.

Method Summary

Modifier and Type	Method	Description
DirectedGraph<Vertex,Edge>	forward()	Creates a DirectedGraph that lazily loads data from the `routinggraph` layer of the Optimized Map for Location Library using OptimizedMapLayers.routingGraph().
static DirectedGraph<Vertex,Edge>	forward(RoutingGraphLayer routingGraphLayer)
DirectedGraph<Vertex,Edge>	reverse()	Creates the reversed DirectedGraph which allows to navigate the topology backwards by flipping all edges.

Graphs

public Graphs(OptimizedMapLayers optimizedMap)

Creates a Graphs from an Optimized Map for Location Library.

Method Details

forward

public DirectedGraph<Vertex,Edge> forward()

Creates a DirectedGraph that lazily loads data from the `routinggraph` layer of the Optimized Map for Location Library using OptimizedMapLayers.routingGraph().

reverse

public DirectedGraph<Vertex,Edge> reverse()

Creates the reversed DirectedGraph which allows to navigate the topology backwards by flipping all edges.

A reversed graph is a DirectedGraph in which the DirectedGraph.getOutEdgeIterator(V) method applied to a Vertex `A`, returns the edges that have `A` as a target in the forward graph.

The returned vertices and edges are the same as the one returned from the forward graph and can be used directly to query vertex and edge PropertyMaps.

The reversed graph is not offering the same performance as the forward graph.
