Is it possible to remove a custom weighting while supplying the algoOpts to the createAlgo method? Where should I be looking to customise this if it doesn’t exist already?
I don’t really understand the question, but you should be able to extend GraphHopper to do almost everything you want. I would probably start at the createAlgo method or the place where this method gets called.
This is my calcPaths method where I can dynamically add a weigthing to my algoOpts,
AvoidEdgesWeighting avoidPathWeighting = new AvoidEdgesWeighting(algoOpts.getWeighting()); avoidPathWeighting.setEdgePenaltyFactor(5); algoOpts = AlgorithmOptions.start(algoOpts).algorithm(Parameters.Algorithms.ASTAR_BI) .weighting(avoidPathWeighting).build();
Now what if my want to remove a weighting instead of adding?
