Getting all possible directions from a geo point in osm2po

Wanted to share some of my code I use to get all possible routes from a random geopoint in osm2po.

 Graph graph = loadGraph();

 OverlayNode node = new OverlayNode(lat, lon);
 if (node.snap(graph, (int[])null)) {
        List<Integer> edges = new LinkedList<>();
        edges.add(node.getEdgeIdx());
        int reverseId = graph.findReverseEdge(node.getEdgeIdx());

        if (reverseId > 0) {
            edges.add(reverseId);
        }
        for (int edgeIdx : edges) {
            routeFrom(edgeIdx);
        }
    }

Seems to work like I want to work (only getting the reverse edge if it's drivable) - but is this the correct way to do this or is there already a method that will give me all edges for a given point?
