Class DocumentServiceClient (2.56.0)

GitHub RepositoryProduct Reference

Service Description: Service to call Cloud DocumentAI to manage document collection (dataset).

This class provides the ability to make remote calls to the backing service through method calls that map to API methods. Sample code to get started:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 try (DocumentServiceClient documentServiceClient = DocumentServiceClient.create()) {
   DatasetName dataset = DatasetName.of("[PROJECT]", "[LOCATION]", "[PROCESSOR]");
   GetDocumentResponse response = documentServiceClient.getDocument(dataset);
 }

Note: close() needs to be called on the DocumentServiceClient object to clean up resources such as threads. In the example above, try-with-resources is used, which automatically calls close().

Methods
Method Description Method Variants

UpdateDataset

Updates metadata associated with a dataset. Note that this method requires the documentai.googleapis.com/datasets.update permission on the project, which is highly privileged. A user or service account with this permission can create new processors that can interact with any gcs bucket in your project.

Request object method variants only take one parameter, a request object, which must be constructed before the call.

  • updateDatasetAsync(UpdateDatasetRequest request)

Methods that return long-running operations have "Async" method variants that return OperationFuture, which is used to track polling of the service.

  • updateDatasetAsync(Dataset dataset, FieldMask updateMask)

Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

See the individual methods for example code.

Many parameters require resource names to be formatted in a particular way. To assist with these names, this class includes a format method for each type of name, and additionally a parse method to extract the individual identifiers contained within names that are returned.

This class can be customized by passing in a custom instance of DocumentServiceSettings to create(). For example:

To customize credentials:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 DocumentServiceSettings documentServiceSettings =
     DocumentServiceSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 DocumentServiceClient documentServiceClient =
     DocumentServiceClient.create(documentServiceSettings);

To customize the endpoint:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 DocumentServiceSettings documentServiceSettings =
     DocumentServiceSettings.newBuilder().setEndpoint(myEndpoint).build();
 DocumentServiceClient documentServiceClient =
     DocumentServiceClient.create(documentServiceSettings);

To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over the wire:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 DocumentServiceSettings documentServiceSettings =
     DocumentServiceSettings.newHttpJsonBuilder().build();
 DocumentServiceClient documentServiceClient =
     DocumentServiceClient.create(documentServiceSettings);
