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.

listWorkflowsAsync(request, options)

listWorkflowsAsync(request?: protos.google.cloud.workflows.v1beta.IListWorkflowsRequest, options?: CallOptions): AsyncIterable<protos.google.cloud.workflows.v1beta.IWorkflow>;

Equivalent to listWorkflows, 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.cloud.workflows.v1beta.IListWorkflowsRequest request

The request object that will be sent.
CallOptions options

Call options. See CallOptions for more details.
Returns
Type Description
AsyncIterable<protos.google.cloud.workflows.v1beta.IWorkflow>

{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 [Workflow]. 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.

listWorkflowsStream(request, options)

listWorkflowsStream(request?: protos.google.cloud.workflows.v1beta.IListWorkflowsRequest, options?: CallOptions): Transform;

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

Parameters
Type Name Description
protos.google.cloud.workflows.v1beta.IListWorkflowsRequest 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 [Workflow] 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 listWorkflowsAsync() 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.
