Example 7 with InstructionList

use of com.graphhopper.util.InstructionList in project graphhopper by graphhopper.

the class Examples method routing.

@Test

    // note: turn off instructions and calcPoints if you just need the distance or time
    // information to make calculation and transmission faster
    // Optionally set specific locale for instruction information, supports already over 25 languages,
    // defaults to English

    ResponsePath res = fullRes.getBest();
    // get path geometry information (latitude, longitude and optionally elevation)
    PointList pl = res.getPoints();
    // distance of the full path, in meter
    double distance = res.getDistance();
    // time of the full path, in milliseconds
    long millis = res.getTime();
    // get information per turn instruction
    InstructionList il = res.getInstructions();
    for (Instruction i : il) {
    // System.out.println(i.getName());
