Constructor

new CloudFunctionsServiceClient(optionsopt, gaxInstanceopt)

Construct an instance of CloudFunctionsServiceClient.

Parameters:
Name Type Attributes Description
options object <optional>

The configuration object. The options accepted by the constructor are described in detail in this document. The common options are:

Properties
Name Type Attributes Description
credentials object <optional>

Credentials object.

Properties
Name Type Attributes Description

private_key string <optional>
email string <optional>

Account email address. Required when using a .pem or .p12 keyFilename.
keyFilename string <optional>

Full path to the a .json, .pem, or .p12 key downloaded from the Google Developers Console. If you provide a path to a JSON file, the projectId option below is not necessary. NOTE: .pem and .p12 require you to specify options.email as well.
port number <optional>

The port on which to connect to the remote host.
projectId string <optional>

The project ID from the Google Developer's Console, e.g. 'grape-spaceship-123'. We will also check the environment variable GCLOUD_PROJECT for your project ID. If your app is running in an environment which supports Application Default Credentials, your project ID will be detected automatically.
apiEndpoint string <optional>

The domain name of the API remote host.

Methods

cancelOperation(request, optionsopt, callbackopt) → {Promise}

Starts asynchronous cancellation on a long-running operation. The server makes a best effort to cancel the operation, but success is not guaranteed. If the server doesn't support this method, it returns google.rpc.Code.UNIMPLEMENTED. Clients can use Operations.GetOperation or other methods to check whether the cancellation succeeded or whether the operation completed despite cancellation. On successful cancellation, the operation is not deleted; instead, it becomes an operation with an Operation.error value with a google.rpc.Status.code of 1, corresponding to Code.CANCELLED.

Parameters:
Name Type Attributes Description
request Object

The request object that will be sent.

Properties
Name Type Description
name string

The name of the operation resource to be cancelled.
options Object <optional>

Optional parameters. You can override the default settings for this call, e.g, timeout, retries, paginations, etc. See gax.CallOptions for the details.
callback function <optional>

The function which will be called with the result of the API call.
Returns:
Type Description
Promise
  • The promise which resolves when API call finishes. The promise has a method named "cancel" which cancels the ongoing API call.

Parameters:
Name Type Attributes Description
request Object

The request object that will be sent.

Properties
Name Type Description
parent string

The project and location from which the function should be listed, specified in the format projects/* /locations/* If you want to list functions in all locations, use "-" in place of a location. When listing functions in all locations, if one or more location(s) are unreachable, the response will contain functions from all reachable locations along with the names of any unreachable locations.
pageSize number

Returns:
Type Description
Object

An iterable Object that allows async iteration. When you iterate the returned iterable, each element will be an object representing CloudFunction. 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 for more details and examples.
Example
  /**
   * This snippet has been automatically generated and should be regarded as a code template only.
   * It will require modifications to work.

const iterable = client.listLocationsAsync(request);
for await (const response of iterable) {
  // process response
}
```

listOperationsAsync(request, optionsopt) → {Object}
