Hi, i'm not sure if i really understand what you want. But maybe it helps if you take a look atOSMreader.processWay, where barrier nodes are converted to towernodes? I for my part would use this method, which assigns OSMnodes to GraphHopper edges anyhow, and directly covert the nodeflags directly to edgeflags.
