Example 66 with GraphHopper

use of com.graphhopper.GraphHopper in project graphhopper by graphhopper.

the class RoutingExampleTC method createGraphHopperInstance.

// see RoutingExample for more details
static GraphHopper createGraphHopperInstance(String ghLoc) {
    GraphHopper hopper = new GraphHopper();
    hopper.setOSMFile(ghLoc);
    hopper.setGraphHopperLocation("target/routing-tc-graph-cache");

    // from OSM

    hopper.setProfiles(profile);
    // enable CH for our profile. since turn costs are enabled this will take more time and memory to prepare than
    // without turn costs.
