Class v1beta3.MessagesV1Beta3Client (2.0.1)

The Dataflow Messages API is used for monitoring the progress of Dataflow jobs. v1beta3

Package

Constructors

(constructor)(opts, gaxInstance)

constructor(opts?: ClientOptions, gaxInstance?: typeof gax | typeof gax.fallback);

Construct an instance of MessagesV1Beta3Client.

Parameters

Name	Description
opts	`ClientOptions`
gaxInstance	`typeof gax \| typeof gax.fallback` : loaded instance of `google-gax`. Useful if you need to avoid loading the default gRPC version and want to use the fallback HTTP implementation. Load only fallback version and pass it to the constructor: ``` const gax = require('google-gax/build/src/fallback'); // avoids loading google-gax with gRPC const client = new MessagesV1Beta3Client({fallback: 'rest'}, gax); ```

Properties

apiEndpoint

static get apiEndpoint(): string;

The DNS address for this API service - same as servicePath(), exists for compatibility reasons.

auth

auth: gax.GoogleAuth;

descriptors

descriptors: Descriptors;

innerApiCalls

innerApiCalls: {
        [name: string]: Function;
    };

messagesV1Beta3Stub

messagesV1Beta3Stub?: Promise<{
        [name: string]: Function;
    }>;

port

static get port(): number;

The port for this API service.

scopes

static get scopes(): string[];

The scopes needed to make gRPC calls for every method defined in this service.

servicePath

static get servicePath(): string;

The DNS address for this API service.

warn

warn: (code: string, message: string, warnType?: string) => void;

Methods

close()

close(): Promise<void>;

Terminate the gRPC channel and close the client.

The client will no longer be usable and all future behavior is undefined.

Returns

Type	Description
Promise<void>	{Promise} A promise that resolves when the client is closed.

getProjectId()

getProjectId(): Promise<string>;

Returns

Type	Description
Promise<string>

getProjectId(callback)

getProjectId(callback: Callback<string, undefined, undefined>): void;

Parameter

Name	Description
callback	`Callback<string, undefined, undefined>`

Returns

Type	Description
void

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.

listJobMessages(request, options)

listJobMessages(request?: protos.google.dataflow.v1beta3.IListJobMessagesRequest, options?: CallOptions): Promise<[
        protos.google.dataflow.v1beta3.IJobMessage[],
        protos.google.dataflow.v1beta3.IListJobMessagesRequest | null,
        protos.google.dataflow.v1beta3.IListJobMessagesResponse
    ]>;

Request the job status.

To request the status of a job, we recommend using projects.locations.jobs.messages.list with a [regional endpoint] (https://cloud.google.com/dataflow/docs/concepts/regional-endpoints). Using projects.jobs.messages.list is not recommended, as you can only request the status of jobs that are running in us-central1.

Parameters

Name	Description
request	`protos.google.dataflow.v1beta3.IListJobMessagesRequest` The request object that will be sent.
options	`CallOptions` Call options. See CallOptions for more details.

Returns

Type Description

Promise<[ protos.google.dataflow.v1beta3.IJobMessage[], protos.google.dataflow.v1beta3.IListJobMessagesRequest | null, protos.google.dataflow.v1beta3.IListJobMessagesResponse ]>

{Promise} - The promise which resolves to an array. The first element of the array is Array of [JobMessage]. 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 listJobMessagesAsync() 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.

listJobMessages(request, options, callback)

listJobMessages(request: protos.google.dataflow.v1beta3.IListJobMessagesRequest, options: CallOptions, callback: PaginationCallback<protos.google.dataflow.v1beta3.IListJobMessagesRequest, protos.google.dataflow.v1beta3.IListJobMessagesResponse | null | undefined, protos.google.dataflow.v1beta3.IJobMessage>): void;

Parameters

Name	Description
request	`protos.google.dataflow.v1beta3.IListJobMessagesRequest`
options	`CallOptions`
callback	`PaginationCallback<protos.google.dataflow.v1beta3.IListJobMessagesRequest, protos.google.dataflow.v1beta3.IListJobMessagesResponse \| null \| undefined, protos.google.dataflow.v1beta3.IJobMessage>`

Returns

Type	Description
void

listJobMessages(request, callback)

listJobMessages(request: protos.google.dataflow.v1beta3.IListJobMessagesRequest, callback: PaginationCallback<protos.google.dataflow.v1beta3.IListJobMessagesRequest, protos.google.dataflow.v1beta3.IListJobMessagesResponse | null | undefined, protos.google.dataflow.v1beta3.IJobMessage>): void;

Parameters

Name	Description
request	`protos.google.dataflow.v1beta3.IListJobMessagesRequest`
callback	`PaginationCallback<protos.google.dataflow.v1beta3.IListJobMessagesRequest, protos.google.dataflow.v1beta3.IListJobMessagesResponse \| null \| undefined, protos.google.dataflow.v1beta3.IJobMessage>`

Returns

Type	Description
void

listJobMessagesAsync(request, options)

listJobMessagesAsync(request?: protos.google.dataflow.v1beta3.IListJobMessagesRequest, options?: CallOptions): AsyncIterable<protos.google.dataflow.v1beta3.IJobMessage>;

Equivalent to listJobMessages, but returns an iterable object.

for-await-of syntax is used with the iterable to get response elements on-demand.

Parameters

Name	Description
request	`protos.google.dataflow.v1beta3.IListJobMessagesRequest` The request object that will be sent.
options	`CallOptions` Call options. See CallOptions for more details.

Returns

Type

Description

AsyncIterable<protos.google.dataflow.v1beta3.IJobMessage>

{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 [JobMessage]. 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.

listJobMessagesStream(request, options)

listJobMessagesStream(request?: protos.google.dataflow.v1beta3.IListJobMessagesRequest, options?: CallOptions): Transform;

Equivalent to method.name.toCamelCase(), but returns a NodeJS Stream object.

Parameters

Name	Description
request	`protos.google.dataflow.v1beta3.IListJobMessagesRequest` The request object that will be sent.
options	`CallOptions` Call options. See CallOptions for more details.

Returns

Type Description

Transform

{Stream} An object stream which emits an object representing [JobMessage] on 'data' event. The client library will perform auto-pagination by default: it will call the API as many times as needed. Note that it can affect your quota. We recommend using listJobMessagesAsync() 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.
