Shipment Tracking

FleetEngineShipmentLocationProvider class

google.maps.journeySharing.FleetEngineShipmentLocationProvider class

Shipment location provider.

This class extends PollingLocationProvider.

Access by calling const {FleetEngineShipmentLocationProvider} = await google.maps.importLibrary("journeySharing").
See Libraries in the Maps JavaScript API.
FleetEngineShipmentLocationProvider
FleetEngineShipmentLocationProvider(options)
Parameters: 
Creates a new location provider for Fleet Engine shipment tracking.
trackingId
Type:  string
The tracking ID for the task that this location provider observes. Set this field to begin tracking.
Inherited: isPolling, pollingIntervalMillis
refresh
refresh()
Parameters:  None
Return Value:  void
Explicitly refreshes the tracked location.
Inherited: addListener
error
function(event)
Arguments: 
Event that is triggered when the location provider encounters an error.
update
function(event)

FleetEngineShipmentLocationProviderOptions interface

google.maps.journeySharing.FleetEngineShipmentLocationProviderOptions interface

Options for shipment 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 ShipmentPolylineCustomizationFunctionParams for a list of supplied parameters and their uses.
deliveryVehicleMarkerCustomization optional
Type:  (function(ShipmentMarkerCustomizationFunctionParams): void)|MarkerOptions optional
Customization applied to the delivery 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.

    See ShipmentMarkerCustomizationFunctionParams for a list of supplied parameters and their uses.
destinationMarkerCustomization optional
Type:  (function(ShipmentMarkerCustomizationFunctionParams): void)|MarkerOptions optional
Customization applied to the 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 ShipmentMarkerCustomizationFunctionParams 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, Infinity, or a negative value disables automatic location updates. A new location update is fetched once if the tracking ID parameter (for example, the shipment tracking ID of the shipment location provider), or a filtering option (for example, viewport bounds or attribute filters for fleet location providers) changes.

The default, and minimum, polling interval is 5000 milliseconds. If you set the polling interval to a lower positive value, 5000 is stored and 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 ShipmentPolylineCustomizationFunctionParams for a list of supplied parameters and their uses.
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 ShipmentPolylineCustomizationFunctionParams for a list of supplied parameters and their uses.
trackingId optional
Type:  string optional
The tracking ID of the task to track immediately after the location provider is instantiated. If not specified, the location provider does not start tracking any task; use FleetEngineShipmentLocationProvider.trackingId to set the tracking ID and begin tracking.

FleetEngineShipmentLocationProviderUpdateEvent interface

google.maps.journeySharing.FleetEngineShipmentLocationProviderUpdateEvent interface

The event object passed to the event handler when the FleetEngineShipmentLocationProvider.update event is triggered.
taskTrackingInfo optional
Type:  TaskTrackingInfo optional
The task tracking info structure returned by the update. Unmodifiable.
