Class SessionsClient (0.34.0)

public class SessionsClient implements BackgroundResource

Service Description: A session represents an interaction with a user. You retrieve user input and pass it to the DetectIntent method to determine user intent and respond.

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 (SessionsClient sessionsClient = SessionsClient.create()) {
   DetectIntentRequest request =
       DetectIntentRequest.newBuilder()
           .setSession(
               SessionName.ofProjectLocationAgentSessionName(
                       "[PROJECT]", "[LOCATION]", "[AGENT]", "[SESSION]")
                   .toString())
           .setQueryParams(QueryParameters.newBuilder().build())
           .setQueryInput(QueryInput.newBuilder().build())
           .setOutputAudioConfig(OutputAudioConfig.newBuilder().build())
           .build();
   DetectIntentResponse response = sessionsClient.detectIntent(request);
 }

Note: close() needs to be called on the SessionsClient 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:

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.
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.
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 SessionsSettings 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
 SessionsSettings sessionsSettings =
     SessionsSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 SessionsClient sessionsClient = SessionsClient.create(sessionsSettings);

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
 SessionsSettings sessionsSettings =
     SessionsSettings.newBuilder().setEndpoint(myEndpoint).build();
 SessionsClient sessionsClient = SessionsClient.create(sessionsSettings);

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
 SessionsSettings sessionsSettings = SessionsSettings.newHttpJsonBuilder().build();
 SessionsClient sessionsClient = SessionsClient.create(sessionsSettings);

Static Methods

create()

public static final SessionsClient create()

Constructs an instance of SessionsClient with default settings.

Returns
Type	Description
`SessionsClient`

Exceptions
Type	Description
`IOException`

create(SessionsSettings settings)

public static final SessionsClient create(SessionsSettings settings)

Constructs an instance of SessionsClient, using the given settings. The channels are created based on the settings passed in, or defaults for any settings that are not set.

Parameter
Name	Description

Returns
Type	Description
`SessionsClient`

Exceptions
Type	Description
`IOException`

create(SessionsStub stub)

public static final SessionsClient create(SessionsStub stub)

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

Parameter
Name	Description
`stub`	`SessionsStub`

Returns
Type	Description
`SessionsClient`

Constructors

SessionsClient(SessionsSettings settings)

protected SessionsClient(SessionsSettings settings)

Constructs an instance of SessionsClient, 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.

close()

public final void close()

detectIntent(DetectIntentRequest request)

public final DetectIntentResponse detectIntent(DetectIntentRequest request)
