staleLocationThresholdMillis
Type:  number
This Field is read-only. Threshold for stale vehicle location. If the last updated location for the vehicle is older than this threshold, the vehicle will not be displayed.
vehicleId
Type:  string
ID for the vehicle that this location provider observes. Set this field to track a vehicle.
Inherited: isPolling, pollingIntervalMillis
Inherited: addListener
error
function(event)
Arguments: 
Event that is triggered when the location provider encounters an error.

FleetEngineVehicleLocationProviderOptions interface

google.maps.journeySharing.FleetEngineVehicleLocationProviderOptions interface

Options for vehicle location provider.
authTokenFetcher
Provides JSON Web Tokens for authenticating the client to Fleet Engine.
projectId
Type:  string
The consumer's project ID from Google Cloud Console.
activePolylineCustomization optional
Customization applied to the active polyline. An active polyline corresponds to a portion of the route the vehicle is currently traversing through.

Use this field to specify custom styling (such as polyline color) and interactivity (such as click handling).
  • If a PolylineOptions object is specified, the changes specified in it are applied to the polyline after the polyline has been created, overwriting its default options if they exist.
  • If a function is specified, it is invoked once when the polyline is created. (On this invocation, the isNew parameter in the function parameters object is set to true.) Additionally, this function is invoked when the polyline's coordinates change, or when the location provider receives data from Fleet Engine, regardless of whether the data corresponding to this polyline have changed.

    See VehiclePolylineCustomizationFunctionParams for a list of supplied parameters and their uses.
destinationMarkerCustomization optional
Customization applied to the vehicle trip destination marker.

Use this field to specify custom styling (such as marker icon) and interactivity (such as click handling).
  • If a MarkerOptions object is specified, the changes specified in it are applied to the marker after the marker has been created, overwriting its default options if they exist.
  • If a function is specified, it is invoked once when the marker is created, before it is added to the map view. (On this invocation, the isNew parameter in the function parameters object is set to true.) Additionally, this function is invoked when the location provider receives data from Fleet Engine, regardless of whether the data corresponding to this marker have changed.

    See VehicleWaypointMarkerCustomizationFunctionParams for a list of supplied parameters and their uses.
intermediateDestinationMarkerCustomization optional
Customization applied to the vehicle trip intermediate destination markers.

Use this field to specify custom styling (such as marker icon) and interactivity (such as click handling).
  • If a MarkerOptions object is specified, the changes specified in it are applied to the marker after the marker has been created, overwriting its default options if they exist.
  • If a function is specified, it is invoked once when the marker is created, before it is added to the map view. (On this invocation, the isNew parameter in the function parameters object is set to true.) Additionally, this function is invoked when the location provider receives data from Fleet Engine, regardless of whether the data corresponding to this marker have changed.

    See VehicleWaypointMarkerCustomizationFunctionParams for a list of supplied parameters and their uses.
originMarkerCustomization optional
Customization applied to the vehicle trip origin marker.

Use this field to specify custom styling (such as marker icon) and interactivity (such as click handling).
  • If a MarkerOptions object is specified, the changes specified in it are applied to the marker after the marker has been created, overwriting its default options if they exist.
  • If a function is specified, it is invoked once when the marker is created, before it is added to the map view. (On this invocation, the isNew parameter in the function parameters object is set to true.) Additionally, this function is invoked when the location provider receives data from Fleet Engine, regardless of whether the data corresponding to this marker have changed.

    See VehicleWaypointMarkerCustomizationFunctionParams for a list of supplied parameters and their uses.
pollingIntervalMillis optional
Type:  number optional
Minimum time between fetching location updates in milliseconds. If it takes longer than pollingIntervalMillis to fetch a location update, the next location update is not started until the current one finishes.

Setting this value to 0 disables recurring location updates. A new location update is fetched if any of the parameters observed by the location provider changes.

The default polling interval is 5000 milliseconds, the minimum interval. If you set the polling interval to a lower non-zero value, 5000 is used.
remainingPolylineCustomization optional
Customization applied to the remaining polyline. A remaining polyline corresponds to a portion of the route the vehicle has not yet started traversing through.

Use this field to specify custom styling (such as polyline color) and interactivity (such as click handling).
  • If a PolylineOptions object is specified, the changes specified in it are applied to the polyline after the polyline has been created, overwriting its default options if they exist.
  • If a function is specified, it is invoked once when the polyline is created. (On this invocation, the isNew parameter in the function parameters object is set to true.) Additionally, this function is invoked when the polyline's coordinates change, or when the location provider receives data from Fleet Engine, regardless of whether the data corresponding to this polyline have changed.

    See VehiclePolylineCustomizationFunctionParams for a list of supplied parameters and their uses.
staleLocationThresholdMillis optional
Type:  number optional
Threshold for stale vehicle location. If the last updated location for the vehicle is older this threshold, the vehicle will not be displayed. Defaults to 24 hours in milliseconds. If the threshold is less than 0, or Infinity, the threshold will be ignored and the vehicle location will not be considered stale.
takenPolylineCustomization optional
Customization applied to the taken polyline. A taken polyline corresponds to a portion of the route the vehicle has already traversed through.

Use this field to specify custom styling (such as polyline color) and interactivity (such as click handling).
  • If a PolylineOptions object is specified, the changes specified in it are applied to the polyline after the polyline has been created, overwriting its default options if they exist.
  • If a function is specified, it is invoked once when the polyline is created. (On this invocation, the isNew parameter in the function parameters object is set to true.) Additionally, this function is invoked when the polyline's coordinates change, or when the location provider receives data from Fleet Engine, regardless of whether the data corresponding to this polyline have changed.

    See VehiclePolylineCustomizationFunctionParams for a list of supplied parameters and their uses.
vehicleId optional
Type:  string optional
The vehicle ID to track immediately after the location provider is instantiated. If not specified, the location provider does not start tracking any vehicle; use FleetEngineVehicleLocationProvider.vehicleId to set the ID and begin tracking.
vehicleMarkerCustomization optional
Type:  (function(VehicleMarkerCustomizationFunctionParams): void)|MarkerOptions optional
Customization applied to the vehicle marker.

Use this field to specify custom styling (such as marker icon) and interactivity (such as click handling).
  • If a MarkerOptions object is specified, the changes specified in it are applied to the marker after the marker has been created, overwriting its default options if they exist.
  • If a function is specified, it is invoked once when the marker is created, before it is added to the map view. (On this invocation, the isNew parameter in the function parameters object is set to true.) Additionally, this function is invoked when the location provider receives data from Fleet Engine, regardless of whether the data corresponding to this marker have changed.
