Product Reference

Service Description: Manages versions of a service.

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 (VersionsClient versionsClient = VersionsClient.create()) {
   GetVersionRequest request =
       GetVersionRequest.newBuilder()
           .setName("name3373707")
           .setView(VersionView.forNumber(0))
           .build();
   Version response = versionsClient.getVersion(request);
 }
 

Note: close() needs to be called on the VersionsClient 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
ListVersions	Lists the versions of a service.	Request object method variants only take one parameter, a request object, which must be constructed before the call. listVersions(ListVersionsRequest request) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. listVersionsPagedCallable() listVersionsCallable()
GetVersion	Gets the specified Version resource. By default, only a BASIC_VIEW will be returned. Specify the FULL_VIEW parameter to get the full resource.	Request object method variants only take one parameter, a request object, which must be constructed before the call. getVersion(GetVersionRequest request) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. getVersionCallable()
CreateVersion	Deploys code and resource files to a new version.	Request object method variants only take one parameter, a request object, which must be constructed before the call. createVersionAsync(CreateVersionRequest request) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. createVersionOperationCallable() createVersionCallable()
UpdateVersion	Updates the specified Version resource. You can specify the following fields depending on the App Engine environment and type of scaling that the version resource uses: **Standard environment** instance_class *automatic scaling* in the standard environment: automatic_scaling.min_idle_instances automatic_scaling.max_idle_instances automaticScaling.standard_scheduler_settings.max_instances automaticScaling.standard_scheduler_settings.min_instances automaticScaling.standard_scheduler_settings.target_cpu_utilization automaticScaling.standard_scheduler_settings.target_throughput_utilization *basic scaling* or *manual scaling* in the standard environment: serving_status manual_scaling.instances **Flexible environment** serving_status *automatic scaling* in the flexible environment: automatic_scaling.min_total_instances automatic_scaling.max_total_instances automatic_scaling.cool_down_period_sec automatic_scaling.cpu_utilization.target_utilization *manual scaling* in the flexible environment: manual_scaling.instances	Request object method variants only take one parameter, a request object, which must be constructed before the call. updateVersionAsync(UpdateVersionRequest request) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. updateVersionOperationCallable() updateVersionCallable()
DeleteVersion	Deletes an existing Version resource.	Request object method variants only take one parameter, a request object, which must be constructed before the call. deleteVersionAsync(DeleteVersionRequest request) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. deleteVersionOperationCallable() deleteVersionCallable()

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 VersionsSettings 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
 VersionsSettings versionsSettings =
     VersionsSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 VersionsClient versionsClient = VersionsClient.create(versionsSettings);
 

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
 VersionsSettings versionsSettings =
     VersionsSettings.newBuilder().setEndpoint(myEndpoint).build();
 VersionsClient versionsClient = VersionsClient.create(versionsSettings);
 

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
 VersionsSettings versionsSettings = VersionsSettings.newHttpJsonBuilder().build();
 VersionsClient versionsClient = VersionsClient.create(versionsSettings);
