checkBatchProcessDocumentsProgress(name: string): Promise<LROperation<protos.google.cloud.documentai.v1beta1.BatchProcessDocumentsResponse, protos.google.cloud.documentai.v1beta1.OperationMetadata>>;

Check the status of the long running operation returned by batchProcessDocuments().

Parameter

Name	Description
name	`string` The operation name that will be passed.

Returns

Type	Description
Promise<LROperation<protos.google.cloud.documentai.v1beta1.BatchProcessDocumentsResponse, protos.google.cloud.documentai.v1beta1.OperationMetadata>>	{Promise} - The promise which resolves to an object. The decoded operation object has result and metadata field to get information from. Please see the [documentation](https://github.com/googleapis/gax-nodejs/blob/master/client-libraries.md#long-running-operations) for more details and examples.

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.

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.
