Example 1 with FlagEncoderFactory

use of com.graphhopper.routing.util.FlagEncoderFactory in project graphhopper by graphhopper.

the class SpatialRuleLookupHelper method buildAndInjectSpatialRuleIntoGH.

public static void buildAndInjectSpatialRuleIntoGH(GraphHopper graphHopper, CmdArgs args) {
    String spatialRuleLocation = args.get("spatial_rules.location", "");

            final InputStreamReader reader = new InputStreamReader(new FileInputStream(spatialRuleLocation), UTF_CS);
            final SpatialRuleLookup index = SpatialRuleLookupBuilder.buildIndex(new GHJsonFactory().create().fromJson(reader, JsonFeatureCollection.class), "ISO_A3", new CountriesSpatialRuleFactory(), .1, maxBounds);
            logger.info("Set spatial rule lookup with " + index.size() + " rules");
            final FlagEncoderFactory oldFEF = graphHopper.getFlagEncoderFactory();
