-// AUTO-GENERATED DOCUMENTATION AND CLASS.
-/**
- * Service Description: Manages TPU nodes and other resources
- *
- * 
TPU API v1
- *
- * 
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:
- *
- * 
{@code
- * // 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 (TpuClient tpuClient = TpuClient.create()) {
- *   NodeName name = NodeName.of("[PROJECT]", "[LOCATION]", "[NODE]");
- *   Node response = tpuClient.getNode(name);
- * }
- * }

- *
- * 
Note: close() needs to be called on the TpuClient object to clean up resources such as
- * threads. In the example above, try-with-resources is used, which automatically calls close().
- *
- * 
The surface of this class includes several types of Java methods for each of the API's
- * methods:
- *
- * 
    
- *   
  1. A "flattened" method. With this type of method, the fields of the request type have been
- *       converted into function parameters. It may be the case that not all fields are available as
- *       parameters, and not every API method will have a flattened method entry point.
- *   
  2. A "request object" method. This type of method only takes one parameter, a request object,
- *       which must be constructed before the call. Not every API method will have a request object
- *       method.
- *   
  3. A "callable" method. This type of method takes no parameters and returns an immutable API
- *       callable object, which can be used to initiate calls to the service.
- * 

- *
- * 
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 TpuSettings to create(). For
- * example:
- *
- * 
To customize credentials:
- *
- * 
{@code
- * // 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
- * TpuSettings tpuSettings =
- *     TpuSettings.newBuilder()
- *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
- *         .build();
- * TpuClient tpuClient = TpuClient.create(tpuSettings);
- * }

- *
- * 
To customize the endpoint:
- *
- * 
{@code
- * // 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
- * TpuSettings tpuSettings = TpuSettings.newBuilder().setEndpoint(myEndpoint).build();
- * TpuClient tpuClient = TpuClient.create(tpuSettings);
- * }

- *
- * 
Please refer to the GitHub repository's samples for more quickstart code snippets.

-// AUTO-GENERATED DOCUMENTATION AND CLASS.
-/**
- * Settings class to configure an instance of {@link TpuClient}.
- *
- * 
The default instance has everything set to sensible defaults:
- *
- * 
    
- *   
  • The default service address (tpu.googleapis.com) and default port (443) are used.
- *   
  • Credentials are acquired automatically through Application Default Credentials.
- *   
  • Retries are configured for idempotent methods but not for non-idempotent methods.
- * 

- *
- * 
The builder of this class is recursive, so contained classes are themselves builders. When
- * build() is called, the tree of builders is called to create the complete settings object.
- *
- * 
For example, to set the total timeout of getNode to 30 seconds:
- *
- * 
{@code
- * // 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
- * TpuSettings.Builder tpuSettingsBuilder = TpuSettings.newBuilder();
- * tpuSettingsBuilder
- *     .getNodeSettings()
- *     .setRetrySettings(
- *         tpuSettingsBuilder.getNodeSettings().getRetrySettings().toBuilder()
- *             .setTotalTimeout(Duration.ofSeconds(30))
- *             .build());
- * TpuSettings tpuSettings = tpuSettingsBuilder.build();
- * }

-/**
- * Settings class to configure an instance of {@link TpuStub}.
- *
- * 
The default instance has everything set to sensible defaults:
- *
- * 
    
- *   
  • The default service address (tpu.googleapis.com) and default port (443) are used.
- *   
  • Credentials are acquired automatically through Application Default Credentials.
- *   
  • Retries are configured for idempotent methods but not for non-idempotent methods.
- * 

- *
- * 
The builder of this class is recursive, so contained classes are themselves builders. When
- * build() is called, the tree of builders is called to create the complete settings object.
- *
- * 
For example, to set the total timeout of getNode to 30 seconds:
- *
- * 
{@code
- * // 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
- * TpuStubSettings.Builder tpuSettingsBuilder = TpuStubSettings.newBuilder();
- * tpuSettingsBuilder
- *     .getNodeSettings()
- *     .setRetrySettings(
- *         tpuSettingsBuilder.getNodeSettings().getRetrySettings().toBuilder()
- *             .setTotalTimeout(Duration.ofSeconds(30))
- *             .build());
- * TpuStubSettings tpuSettings = tpuSettingsBuilder.build();
- * }

-/**
- * Service Description: Manages TPU nodes and other resources
- *
- * 
TPU API v2alpha1
- *
- * 
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:
- *
- * 
{@code
- * // 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 (TpuClient tpuClient = TpuClient.create()) {
- *   NodeName name = NodeName.of("[PROJECT]", "[LOCATION]", "[NODE]");
- *   Node response = tpuClient.getNode(name);
- * }
- * }

- *
- * 
Note: close() needs to be called on the TpuClient object to clean up resources such as
- * threads. In the example above, try-with-resources is used, which automatically calls close().
- *
- * 
The surface of this class includes several types of Java methods for each of the API's
- * methods:
- *
- * 
    
- *   
  1. A "flattened" method. With this type of method, the fields of the request type have been
- *       converted into function parameters. It may be the case that not all fields are available as
- *       parameters, and not every API method will have a flattened method entry point.
- *   
  2. A "request object" method. This type of method only takes one parameter, a request object,
- *       which must be constructed before the call. Not every API method will have a request object
- *       method.
- *   
  3. A "callable" method. This type of method takes no parameters and returns an immutable API
- *       callable object, which can be used to initiate calls to the service.
- * 

- *
- * 
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 TpuSettings to create(). For
- * example:
- *
- * 
To customize credentials:
- *
- * 
{@code
- * // 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
- * TpuSettings tpuSettings =
- *     TpuSettings.newBuilder()
- *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
- *         .build();
- * TpuClient tpuClient = TpuClient.create(tpuSettings);
- * }

- *
- * 
To customize the endpoint:
- *
- * 
{@code
- * // 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
- * TpuSettings tpuSettings = TpuSettings.newBuilder().setEndpoint(myEndpoint).build();
- * TpuClient tpuClient = TpuClient.create(tpuSettings);
- * }

- *
- * 
Please refer to the GitHub repository's samples for more quickstart code snippets.

-// AUTO-GENERATED DOCUMENTATION AND CLASS.
-/**
- * Settings class to configure an instance of {@link TpuClient}.
- *
- * 
The default instance has everything set to sensible defaults:
- *
- * 
    
- *   
  • The default service address (tpu.googleapis.com) and default port (443) are used.
- *   
  • Credentials are acquired automatically through Application Default Credentials.
- *   
  • Retries are configured for idempotent methods but not for non-idempotent methods.
- * 

- *
- * 
The builder of this class is recursive, so contained classes are themselves builders. When
- * build() is called, the tree of builders is called to create the complete settings object.
- *
- * 
For example, to set the total timeout of getNode to 30 seconds:
- *
- * 
{@code
- * // 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
- * TpuSettings.Builder tpuSettingsBuilder = TpuSettings.newBuilder();
- * tpuSettingsBuilder
- *     .getNodeSettings()
- *     .setRetrySettings(
- *         tpuSettingsBuilder.getNodeSettings().getRetrySettings().toBuilder()
- *             .setTotalTimeout(Duration.ofSeconds(30))
- *             .build());
- * TpuSettings tpuSettings = tpuSettingsBuilder.build();
- * }

-// AUTO-GENERATED DOCUMENTATION AND CLASS.
-/**
- * Settings class to configure an instance of {@link TpuStub}.
- *
- * 
The default instance has everything set to sensible defaults:
- *
- * 
    
- *   
  • The default service address (tpu.googleapis.com) and default port (443) are used.
- *   
  • Credentials are acquired automatically through Application Default Credentials.
- *   
  • Retries are configured for idempotent methods but not for non-idempotent methods.
- * 

- *
- * 
The builder of this class is recursive, so contained classes are themselves builders. When
- * build() is called, the tree of builders is called to create the complete settings object.
- *
- * 
For example, to set the total timeout of getNode to 30 seconds:
- *
- * 
{@code
- * // 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
- * TpuStubSettings.Builder tpuSettingsBuilder = TpuStubSettings.newBuilder();
- * tpuSettingsBuilder
- *     .getNodeSettings()
- *     .setRetrySettings(
- *         tpuSettingsBuilder.getNodeSettings().getRetrySettings().toBuilder()
- *             .setTotalTimeout(Duration.ofSeconds(30))
- *             .build());
- * TpuStubSettings tpuSettings = tpuSettingsBuilder.build();
- * }
