how to get waypoints and trackpoints parameters from current map (google directions api)

function getWptAndTrkptForGpx() {
//  var directionsDisplay = new google.maps.DirectionsRenderer({...}); 
//  it's your DirectionsRenderer variable
  var currentDirections = directionsDisplay.getDirections();
  var route = currentDirections.routes[0];
  var trkpts = route.overview_path;
  var coord = [];
  coord['wpt'] = [];
  coord['trkpt'] = [];

  for ( var i = 0; i < route.legs.length; i++ ) {
    var LegLoc = route.legs[i].start_location;
    var lat = LegLoc.lat();
    var lng = LegLoc.lng();
    var address = route.legs[i].start_address;
    coord['wpt'][i] = [lat, lng, address];

    if ( i+1 == route.legs.length ) {
      var LegLoc = route.legs[i].end_location;
      var lat = LegLoc.lat();
      var lng = LegLoc.lng();
      var address = route.legs[i].end_address;
      coord['wpt'][i+1] = [lat, lng, address];
    }
  }

  for ( var i = 0; i < trkpts.length; i++ ) {
    var LegLoc = trkpts[i];
    var lat = LegLoc.lat();
    var lng = LegLoc.lng();
    coord['trkpt'][i] = [lat, lng];
  }

  return coord;
}

var coord = getWptAndTrkptForGpx();
var waypoints = JSON.stringify(coord.wpt);
var trackpoints = JSON.stringify(coord.trkpt);
