com.google.api.servicecontrol.v1.ServiceControllerClient
All Implemented Interfaces:
BackgroundResource, AutoCloseable
@Generated("by gapic-generator-java") public class ServiceControllerClient extends Object implements BackgroundResource
Service Description: [Google Service Control API](/service-control/overview)

Lets clients check and report operations against a [managed service](https://cloud.google.com/service-management/reference/rpc/google.api/servicemanagement.v1#google.api.servicemanagement.v1.ManagedService).

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:
 // - 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
 try (ServiceControllerClient serviceControllerClient = ServiceControllerClient.create()) {
   CheckRequest request =
       CheckRequest.newBuilder()
           .setServiceName("serviceName-1928572192")
           .setOperation(Operation.newBuilder().build())
           .setServiceConfigId("serviceConfigId650537426")
           .build();
   CheckResponse response = serviceControllerClient.check(request);
 }

Note: close() needs to be called on the ServiceControllerClient 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

Check

Checks whether an operation on a service should be allowed to proceed based on the configuration of the service and related policies. It must be called before the operation is executed.

If feasible, the client should cache the check results and reuse them for 60 seconds. In case of any server errors, the client should rely on the cached results for much longer time to avoid outage. WARNING: There is general 60s delay for the configuration and policy propagation, therefore callers MUST NOT depend on the `Check` method having the latest policy information.

NOTE: the [CheckRequest][google.api.servicecontrol.v1.CheckRequest] has the size limit (wire-format byte size) of 1MB.

This method requires the `servicemanagement.services.check` permission on the specified service. For more information, see [Cloud IAM](https://cloud.google.com/iam).

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

  • check(CheckRequest request)

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

  • checkCallable()

Report

Reports operation results to Google Service Control, such as logs and metrics. It should be called after an operation is completed.

If feasible, the client should aggregate reporting data for up to 5 seconds to reduce API traffic. Limiting aggregation to 5 seconds is to reduce data loss during client crashes. Clients should carefully choose the aggregation time window to avoid data loss risk more than 0.01% for business and compliance reasons.

NOTE: the [ReportRequest][google.api.servicecontrol.v1.ReportRequest] has the size limit (wire-format byte size) of 1MB.

This method requires the `servicemanagement.services.report` permission on the specified service. For more information, see [Google Cloud IAM](https://cloud.google.com/iam).

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

  • report(ReportRequest request)

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

  • reportCallable()

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 ServiceControllerSettings 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
 ServiceControllerSettings serviceControllerSettings =
     ServiceControllerSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 ServiceControllerClient serviceControllerClient =
     ServiceControllerClient.create(serviceControllerSettings);

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
 ServiceControllerSettings serviceControllerSettings =
     ServiceControllerSettings.newBuilder().setEndpoint(myEndpoint).build();
 ServiceControllerClient serviceControllerClient =
     ServiceControllerClient.create(serviceControllerSettings);

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
 ServiceControllerSettings serviceControllerSettings =
     ServiceControllerSettings.newHttpJsonBuilder().build();
 ServiceControllerClient serviceControllerClient =
     ServiceControllerClient.create(serviceControllerSettings);

  • Constructor Details

    • ServiceControllerClient

      protected ServiceControllerClient(ServiceControllerSettings settings) throws IOException
      Constructs an instance of ServiceControllerClient, using the given settings. This is protected so that it is easy to make a subclass, but otherwise, the static factory methods should be preferred.
      Throws:
      IOException

    • ServiceControllerClient

      protected ServiceControllerClient(ServiceControllerStub stub)

  • Method Details

    • create

      public static final ServiceControllerClient create() throws IOException
      Constructs an instance of ServiceControllerClient with default settings.
      Throws:
      IOException

    • create

      public static final ServiceControllerClient create(ServiceControllerSettings settings) throws IOException
      Constructs an instance of ServiceControllerClient, using the given settings. The channels are created based on the settings passed in, or defaults for any settings that are not set.
      Throws:
      IOException

    • create

      public static final ServiceControllerClient create(ServiceControllerStub stub)
      Constructs an instance of ServiceControllerClient, using the given stub for making calls. This is for advanced usage - prefer using create(ServiceControllerSettings).

    • getSettings

      public final ServiceControllerSettings getSettings()

    • getStub

      public ServiceControllerStub getStub()

    • check

      public final CheckResponse check(CheckRequest request)
      Checks whether an operation on a service should be allowed to proceed based on the configuration of the service and related policies. It must be called before the operation is executed.

      If feasible, the client should cache the check results and reuse them for 60 seconds. In case of any server errors, the client should rely on the cached results for much longer time to avoid outage. WARNING: There is general 60s delay for the configuration and policy propagation, therefore callers MUST NOT depend on the `Check` method having the latest policy information.
