Class CompletionServiceClient (0.31.0)

GitHub RepositoryProduct Reference

Service Description: Service for Auto-Completion.

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 (CompletionServiceClient completionServiceClient = CompletionServiceClient.create()) {
   CompleteQueryRequest request =
       CompleteQueryRequest.newBuilder()
           .setDataStore(
               DataStoreName.ofProjectLocationDataStoreName(
                       "[PROJECT]", "[LOCATION]", "[DATA_STORE]")
                   .toString())
           .setQuery("query107944136")
           .setQueryModel("queryModel-184930495")
           .setUserPseudoId("userPseudoId-1155274652")
           .setIncludeTailSuggestions(true)
           .build();
   CompleteQueryResponse response = completionServiceClient.completeQuery(request);
 }
 

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

Methods
MethodDescriptionMethod Variants

CompleteQuery

Completes the specified user input with keyword suggestions.

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

  • completeQuery(CompleteQueryRequest request)

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

  • completeQueryCallable()

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 CompletionServiceSettings 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
 CompletionServiceSettings completionServiceSettings =
     CompletionServiceSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 CompletionServiceClient completionServiceClient =
     CompletionServiceClient.create(completionServiceSettings);
 

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
 CompletionServiceSettings completionServiceSettings =
     CompletionServiceSettings.newBuilder().setEndpoint(myEndpoint).build();
 CompletionServiceClient completionServiceClient =
     CompletionServiceClient.create(completionServiceSettings);
 

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
 CompletionServiceSettings completionServiceSettings =
     CompletionServiceSettings.newHttpJsonBuilder().build();
 CompletionServiceClient completionServiceClient =
     CompletionServiceClient.create(completionServiceSettings);

Static Methods

create()

public static final CompletionServiceClient create()

Constructs an instance of CompletionServiceClient with default settings.

Returns
TypeDescription
CompletionServiceClient
Exceptions
TypeDescription
IOException

create(CompletionServiceSettings settings)

public static final CompletionServiceClient create(CompletionServiceSettings settings)

Returns
TypeDescription
CompletionServiceClient
Exceptions
TypeDescription

create(CompletionServiceStub stub)

public static final CompletionServiceClient create(CompletionServiceStub stub)

Constructs an instance of CompletionServiceClient, using the given stub for making calls. This is for advanced usage - prefer using create(CompletionServiceSettings).

Parameter

Returns
TypeDescription
CompletionServiceClient

Constructors

CompletionServiceClient(CompletionServiceSettings settings)

protected CompletionServiceClient(CompletionServiceSettings settings)

Constructs an instance of CompletionServiceClient, 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.
