[GraphHopper] Replacement for the GHUtility.getCar* methods

[Peter K]

Hi Adam,

yes, this is the way to go. Just define a static EdgeFilter somewhere:
OUT = new DefaultEdgeFilter(new CarFlagEncoder(), false, true)
and do
graph.getEdges(node, OUT)

Or create a helper method for it. I removed those helper methods from
graphhopper as I don't want to focus graphhopper too much on car-usage.
And so, I would've to remove them or add them for foot, bike, etc ... a
bit too much I thought and what if we later on create multi-modal routing?

Of course some months ago this was easier via getOutgoing/getIncoming
but now it isn't that much harder but a lot more flexible (e.g. you can
combine filters and create custom ones). And a filter like "incoming"
really depends on the vehicle.

Regards,
Peter.
