Class FleetRoutingClient (1.39.0)

Service Description: A service for optimizing vehicle tours.

Validity of certain types of fields:

* google.protobuf.Timestamp * Times are in Unix time: seconds since 1970-01-01T00:00:00+00:00. * seconds must be in [0, 253402300799], i.e. in [1970-01-01T00:00:00+00:00, 9999-12-31T23:59:59+00:00]. * nanos must be unset or set to 0. * google.protobuf.Duration * seconds must be in [0, 253402300799], i.e. in [1970-01-01T00:00:00+00:00, 9999-12-31T23:59:59+00:00]. * nanos must be unset or set to 0. * google.type.LatLng * latitude must be in [-90.0, 90.0]. * longitude must be in [-180.0, 180.0]. * at least one of latitude and longitude must be non-zero.

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:

 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 `ShipmentRoute`s, which are a set of routes to be performed by vehicles minimizing the overall cost. A `ShipmentModel` model consists mainly of `Shipment`s that need to be carried out and `Vehicle`s that can be used to transport the `Shipment`s. The `ShipmentRoute`s assign `Shipment`s to `Vehicle`s. More specifically, they assign a series of `Visit`s 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 `ShipmentRoute`s to `Vehicle`s 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 `ShipmentRoute`s, 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);
