    Returns Tile

detectFeatureClass

  • detectFeatureClass(feature: Feature): "LINE" | "NAVLINK" | "MARKER" | "PLACE" | "ADDRESS" | "AREA" | string | null

  • This method is used to determine the FeatureClass required to edit the feature. The FeatureClass defines how a certain feature behaves when its getting edited.

    By default, the Editor handles all features of geometry type 'LineString' as Line, 'Point' as Marker and '(Multi)Polygon' as Area.

    If you want to edit features with FeatureClass 'NAVLINK', 'PLACE' or 'ADDRESS' this method must be overridden to enable editing of Navlinks, Places or Addresses.

    Parameters

    Returns "LINE" | "NAVLINK" | "MARKER" | "PLACE" | "ADDRESS" | "AREA" | string | null

    the FeatureClass of the feature, or null if the feature should not be editable.

exists

  • exists(feature: { id: number | string }): { feature?: Feature }

  • Validate if a feature is stored in the local provider cache.

    Parameters

    • feature: { id: number | string }

      Object literal containing "id" property.

      • id: number | string

    Returns { feature?: Feature }

    the Feature if it is found, otherwise undefined

findPath

  • Finds the optimal path between two coordinates on a GeoJSON road network, considering various options. By default, the weight function returns the distance of the road segment, a lower distance implies a shorter route and is considered more favorable. If you have specific criteria such as road quality, traffic conditions, or other factors influencing the desirability of a road segment, you can customize the weight function accordingly. Pathfinding will consider only the locally cached data available on the client.

    experimental
    example
    const pathOptions = {
  from: [startLongitude, startLatitude],
  to: [endLongitude, endLatitude],
  // optional
  allowTurn: (turn) => {

    return true;
  },
  // optional
  weight: (data) => {
