string

warn

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

Property Value

Type	Description

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

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

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
    ]>;

Parameters

Type	Description
void

Parameters

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

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

Type	Name	Description
protos.google.dataflow.v1beta3.IListJobMessagesRequest	request	The request object that will be sent.
CallOptions	options	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

Type	Name	Description
protos.google.dataflow.v1beta3.IListJobMessagesRequest	request	The request object that will be sent.
CallOptions	options	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.
