This class provides the ability to make remote calls to the backing service through method calls that map to API methods. Sample code to get started:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:

 try (FleetRoutingClient fleetRoutingClient = FleetRoutingClient.create()) {
   OptimizeToursRequest request =
       OptimizeToursRequest.newBuilder()
           .setParent("parent-995424086")
           .setTimeout(Duration.newBuilder().build())
           .setModel(ShipmentModel.newBuilder().build())
           .addAllInjectedFirstSolutionRoutes(new ArrayList<ShipmentRoute>())
           .setInjectedSolutionConstraint(InjectedSolutionConstraint.newBuilder().build())
           .addAllRefreshDetailsRoutes(new ArrayList<ShipmentRoute>())
           .setInterpretInjectedSolutionsUsingLabels(true)
           .setConsiderRoadTraffic(true)
           .setPopulatePolylines(true)
           .setPopulateTransitionPolylines(true)
           .setAllowLargeDeadlineDespiteInterruptionRisk(true)
           .setUseGeodesicDistances(true)
           .setGeodesicMetersPerSecond(-2129658905)
           .setMaxValidationErrors(-1367418922)
           .setLabel("label102727412")
           .setPopulateTravelStepPolylines(true)
           .build();
   OptimizeToursResponse response = fleetRoutingClient.optimizeTours(request);
 }

Note: close() needs to be called on the FleetRoutingClient object to clean up resources such as threads. In the example above, try-with-resources is used, which automatically calls close().

Methods
Method Description Method Variants

OptimizeTours

Sends an OptimizeToursRequest containing a ShipmentModel and returns an OptimizeToursResponse containing ShipmentRoutes, which are a set of routes to be performed by vehicles minimizing the overall cost.

A ShipmentModel model consists mainly of Shipments that need to be carried out and Vehicles that can be used to transport the Shipments. The ShipmentRoutes assign Shipments to Vehicles. More specifically, they assign a series of Visits to each vehicle, where a Visit corresponds to a VisitRequest, which is a pickup or delivery for a Shipment.

The goal is to provide an assignment of ShipmentRoutes to Vehicles that minimizes the total cost where cost has many components defined in the ShipmentModel.

Request object method variants only take one parameter, a request object, which must be constructed before the call.

  • optimizeTours(OptimizeToursRequest request)

Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

  • optimizeToursCallable()

BatchOptimizeTours

Optimizes vehicle tours for one or more OptimizeToursRequest messages as a batch.

This method is a Long Running Operation (LRO). The inputs for optimization (OptimizeToursRequest messages) and outputs (OptimizeToursResponse messages) are read/written from/to Cloud Storage in user-specified format. Like the OptimizeTours method, each OptimizeToursRequest contains a ShipmentModel and returns an OptimizeToursResponse containing ShipmentRoutes, which are a set of routes to be performed by vehicles minimizing the overall cost.

Request object method variants only take one parameter, a request object, which must be constructed before the call.

  • batchOptimizeToursAsync(BatchOptimizeToursRequest request)

Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

  • batchOptimizeToursOperationCallable()

  • batchOptimizeToursCallable()

See the individual methods for example code.

Many parameters require resource names to be formatted in a particular way. To assist with these names, this class includes a format method for each type of name, and additionally a parse method to extract the individual identifiers contained within names that are returned.

This class can be customized by passing in a custom instance of FleetRoutingSettings to create(). For example:

To customize credentials:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 FleetRoutingSettings fleetRoutingSettings =
     FleetRoutingSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 FleetRoutingClient fleetRoutingClient = FleetRoutingClient.create(fleetRoutingSettings);

To customize the endpoint:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 FleetRoutingSettings fleetRoutingSettings =
     FleetRoutingSettings.newBuilder().setEndpoint(myEndpoint).build();
 FleetRoutingClient fleetRoutingClient = FleetRoutingClient.create(fleetRoutingSettings);

To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over the wire:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 FleetRoutingSettings fleetRoutingSettings = FleetRoutingSettings.newHttpJsonBuilder().build();
 FleetRoutingClient fleetRoutingClient = FleetRoutingClient.create(fleetRoutingSettings);
