Class ApplicationsClient (2.35.0)

Service Description: Manages App Engine applications.

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 (ApplicationsClient applicationsClient = ApplicationsClient.create()) {
   String name = "name3373707";
   Application response = applicationsClient.getApplication(name);
 }

Note: close() needs to be called on the ApplicationsClient 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
GetApplication	Gets information about an application.	Request object method variants only take one parameter, a request object, which must be constructed before the call. getApplication(GetApplicationRequest request) "Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method. getApplication(String name) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. getApplicationCallable()
CreateApplication	Creates an App Engine application for a Google Cloud Platform project. Required fields: `id` - The ID of the target Cloud Platform project. location - The region where you want the App Engine application located. For more information about App Engine applications, see Managing Projects, Applications, and Billing.	Request object method variants only take one parameter, a request object, which must be constructed before the call. createApplicationAsync(CreateApplicationRequest request) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. createApplicationOperationCallable() createApplicationCallable()
UpdateApplication	Updates the specified Application resource. You can update the following fields: `auth_domain` - Google authentication domain for controlling user access to the application. `default_cookie_expiration` - Cookie expiration policy for the application. `iap` - Identity-Aware Proxy properties for the application.	Request object method variants only take one parameter, a request object, which must be constructed before the call. updateApplicationAsync(UpdateApplicationRequest request) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. updateApplicationOperationCallable() updateApplicationCallable()
RepairApplication	Recreates the required App Engine features for the specified App Engine application, for example a Cloud Storage bucket or App Engine service account. Use this method if you receive an error message about a missing feature, for example, Error retrieving the App Engine service account. If you have deleted your App Engine service account, this will not be able to recreate it. Instead, you should attempt to use the IAM undelete API if possible at https://cloud.google.com/iam/reference/rest/v1/projects.serviceAccounts/undelete?apix_params=%7B"name"%3A"projects%2F-%2FserviceAccounts%2Funique_id"%2C"resource"%3A%7B%7D%7D . If the deletion was recent, the numeric ID can be found in the Cloud Console Activity Log.	Request object method variants only take one parameter, a request object, which must be constructed before the call. repairApplicationAsync(RepairApplicationRequest request) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. repairApplicationOperationCallable() repairApplicationCallable()

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 ApplicationsSettings 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
 ApplicationsSettings applicationsSettings =
     ApplicationsSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 ApplicationsClient applicationsClient = ApplicationsClient.create(applicationsSettings);

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
 ApplicationsSettings applicationsSettings =
     ApplicationsSettings.newBuilder().setEndpoint(myEndpoint).build();
 ApplicationsClient applicationsClient = ApplicationsClient.create(applicationsSettings);

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
 ApplicationsSettings applicationsSettings = ApplicationsSettings.newHttpJsonBuilder().build();
 ApplicationsClient applicationsClient = ApplicationsClient.create(applicationsSettings);
