Class VersionsClient (2.45.0)

GitHub RepositoryProduct 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**

*automatic scaling* in the standard environment:

*basic scaling* or *manual scaling* in the standard environment:

**Flexible environment**

*automatic scaling* in the flexible environment:

*manual scaling* in the flexible environment:

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);
