Class DocumentServiceClient

  • All Implemented Interfaces:
    com.google.api.gax.core.BackgroundResource, AutoCloseable
    @Generated("by gapic-generator-java")
public class DocumentServiceClient
extends Object
implements com.google.api.gax.core.BackgroundResource
    Service Description: Service for ingesting [Document][google.cloud.discoveryengine.v1.Document] information of the customer's website.

    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()) {
   DocumentName name =
       DocumentName.ofProjectLocationDataStoreBranchDocumentName(
           "[PROJECT]", "[LOCATION]", "[DATA_STORE]", "[BRANCH]", "[DOCUMENT]");
   Document response = documentServiceClient.getDocument(name);
 }

    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().

    The surface of this class includes several types of Java methods for each of the API's methods:

    1. A "flattened" method. With this type of method, the fields of the request type have been converted into function parameters. It may be the case that not all fields are available as parameters, and not every API method will have a flattened method entry point.
    2. A "request object" method. This type of method only takes one parameter, a request object, which must be constructed before the call. Not every API method will have a request object method.
    3. A "callable" method. This type of method takes no parameters and returns 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);

    • Constructor Detail

      • DocumentServiceClient

        protected DocumentServiceClient​(DocumentServiceSettings settings)
                         throws IOException
        Constructs an instance of DocumentServiceClient, using the given settings. This is protected so that it is easy to make a subclass, but otherwise, the static factory methods should be preferred.
        Throws:
        IOException

    • Method Detail

      • create

        public static final DocumentServiceClient create​(DocumentServiceStub stub)
        Constructs an instance of DocumentServiceClient, using the given stub for making calls. This is for advanced usage - prefer using create(DocumentServiceSettings).

        public final com.google.longrunning.OperationsClient getOperationsClient()
        Returns the OperationsClient that can be used to query the status of a long-running operation returned by another API method call.
