[GraphHopper] How graphhopper handle the barrier=gate?

[John Zhao]

Hi,

I looked into OSMReader.processWay( )
There is already a lot of comments. But it's still not clear to me. :p

I understand GH will create a "virtual" node, with the same lat/lon.
And then create a new edge between the 2 nodes.
But how to block this edge?
set the direction bit of the zero length edge both to false? where is the
code?

// create zero length edge for barrier
createdEdges.addAll(addBarrierEdge(newNodeId, nodeId, wayFlags,
nodeFlags, wayOsmId));

*Best Regards,*
