initialize()

initialize(): Promise<{
        [name: string]: Function;
    }>;

Initialize the client. Performs asynchronous operations (such as authentication) and prepares the client. This function will be called automatically when any class method is called for the first time, but if you need to initialize it before calling an actual method, feel free to call initialize() directly.

You can await on this method if you want to make sure the client is initialized.

Returns

Type	Description
Promise<{ [name: string]: Function; }>	{Promise} A promise that resolves to an authenticated service stub.

listAcceleratorTypes(request, options)

listAcceleratorTypes(request?: protos.google.cloud.tpu.v1.IListAcceleratorTypesRequest, options?: CallOptions): Promise<[
        protos.google.cloud.tpu.v1.IAcceleratorType[],
        protos.google.cloud.tpu.v1.IListAcceleratorTypesRequest | null,
        protos.google.cloud.tpu.v1.IListAcceleratorTypesResponse
    ]>;

Lists accelerator types supported by this API.

Parameters

Name	Description
request	`protos.google.cloud.tpu.v1.IListAcceleratorTypesRequest` The request object that will be sent.
options	`CallOptions` Call options. See CallOptions for more details.

Returns

Type Description

Promise<[ protos.google.cloud.tpu.v1.IAcceleratorType[], protos.google.cloud.tpu.v1.IListAcceleratorTypesRequest | null, protos.google.cloud.tpu.v1.IListAcceleratorTypesResponse ]>

{Promise} - The promise which resolves to an array. The first element of the array is Array of [AcceleratorType]. The client library will perform auto-pagination by default: it will call the API as many times as needed and will merge results from all the pages into this array. Note that it can affect your quota. We recommend using listAcceleratorTypesAsync() method described below for async iteration which you can stop as needed. Please see the [documentation](https://github.com/googleapis/gax-nodejs/blob/master/client-libraries.md#auto-pagination) for more details and examples.

Type

Description

AsyncIterable<protos.google.cloud.tpu.v1.IAcceleratorType>

{Object} An iterable Object that allows [async iteration](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Iteration_protocols). When you iterate the returned iterable, each element will be an object representing [AcceleratorType]. The API will be called under the hood as needed, once per the page, so you can stop the iteration when you don't need more results. Please see the [documentation](https://github.com/googleapis/gax-nodejs/blob/master/client-libraries.md#auto-pagination) for more details and examples.

Example


  /**
   * TODO(developer): Uncomment these variables before running the sample.
   */
  /**
   *  Required. The parent resource name.
   */
  // const parent = 'abc123'
  /**
   *  The maximum number of items to return.
   */
  // const pageSize = 1234
  /**
   *  The next_page_token value returned from a previous List request, if any.
   */
  // const pageToken = 'abc123'
  /**
   *  List filter.
   */
  // const filter = 'abc123'
  /**
   *  Sort results.
   */
  // const orderBy = 'abc123'

  // Imports the Tpu library
  const {TpuClient} = require('@google-cloud/tpu').v1;

  // Instantiates a client
  const tpuClient = new TpuClient();

  async function callListAcceleratorTypes() {
    // Construct request
    const request = {
      parent,
    };

    // Run request
    const iterable = await tpuClient.listAcceleratorTypesAsync(request);
    for await (const response of iterable) {

stopNode(request, options)

stopNode(request?: protos.google.cloud.tpu.v1.IStopNodeRequest, options?: CallOptions): Promise<[
        LROperation<protos.google.cloud.tpu.v1.INode, protos.google.cloud.tpu.v1.IOperationMetadata>,
        protos.google.longrunning.IOperation | undefined,
        {} | undefined
    ]>;

Stops a node.

Parameters

Name	Description
request	`protos.google.cloud.tpu.v1.IStopNodeRequest` The request object that will be sent.
options	`CallOptions` Call options. See CallOptions for more details.

Returns

Type	Description
Promise<[ LROperation<protos.google.cloud.tpu.v1.INode, protos.google.cloud.tpu.v1.IOperationMetadata>, protos.google.longrunning.IOperation \| undefined, {} \| undefined ]>	{Promise} - The promise which resolves to an array. The first element of the array is an object representing a long running operation. Its `promise()` method returns a promise you can `await` for. Please see the [documentation](https://github.com/googleapis/gax-nodejs/blob/master/client-libraries.md#long-running-operations) for more details and examples.

Example


  /**

  /**
   *  The resource name.
   */
  // const name = 'abc123'

  // Imports the Tpu library
  const {TpuClient} = require('@google-cloud/tpu').v1;

  // Instantiates a client
  const tpuClient = new TpuClient();

  async function callStopNode() {
    // Construct request
    const request = {};

    // Run request
    const [operation] = await tpuClient.stopNode(request);
    const [response] = await operation.promise();
    console.log(response);
  }

  callStopNode();
