Class SessionsClient (4.7.4)

public class SessionsClient implements BackgroundResource

Service Description: A service used for session interactions.

For more information, see the API interactions guide.

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 for illustrative purposes only.
 // It may require modifications to work in your environment.
 try (SessionsClient sessionsClient = SessionsClient.create()) {
   SessionName session = SessionName.ofProjectSessionName("[PROJECT]", "[SESSION]");
   QueryInput queryInput = QueryInput.newBuilder().build();
   DetectIntentResponse response = sessionsClient.detectIntent(session, queryInput);
 }

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 for illustrative purposes only.
 // It may require modifications to work in your environment.
 SessionsSettings sessionsSettings =
     SessionsSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 SessionsClient sessionsClient = SessionsClient.create(sessionsSettings);

To customize the endpoint:


 // This snippet has been automatically generated for illustrative purposes only.
 // It may require modifications to work in your environment.
 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 for illustrative purposes only.
 // It may require modifications to work in your environment.
 SessionsSettings sessionsSettings =
     SessionsSettings.newBuilder()
         .setTransportChannelProvider(
             SessionsSettings.defaultHttpJsonTransportProviderBuilder().build())
         .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

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
settings	`SessionsSettings`

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.

Parameter

Name	Description
settings	`SessionsSettings`

SessionsClient(SessionsStub stub)

protected SessionsClient(SessionsStub stub)

Parameter

Name	Description
stub	`SessionsStub`

public boolean awaitTermination(long duration, TimeUnit unit)

Parameters

Name	Description
duration	`long`

close()

public final void close()

detectIntent(DetectIntentRequest request)

public final DetectIntentResponse detectIntent(DetectIntentRequest request)

Processes a natural language query and returns structured, actionable data as a result. This method is not idempotent, because it may cause contexts and session entity types to be updated, which in turn might affect results of future queries.

If you might use Agent Assist or other CCAI products now or in the future, consider using AnalyzeContent instead of DetectIntent. AnalyzeContent has additional functionality for Agent Assist and other CCAI products.

Note: Always use agent versions for production traffic. See Versions and environments.

Sample code:


 // This snippet has been automatically generated for illustrative purposes only.
 // It may require modifications to work in your environment.
 try (SessionsClient sessionsClient = SessionsClient.create()) {
   DetectIntentRequest request =
       DetectIntentRequest.newBuilder()
           .setSession(SessionName.ofProjectSessionName("[PROJECT]", "[SESSION]").toString())
           .setQueryParams(QueryParameters.newBuilder().build())
           .setQueryInput(QueryInput.newBuilder().build())
           .setOutputAudioConfig(OutputAudioConfig.newBuilder().build())
           .setOutputAudioConfigMask(FieldMask.newBuilder().build())
           .setInputAudio(ByteString.EMPTY)
           .build();
   DetectIntentResponse response = sessionsClient.detectIntent(request);
 }

Parameter

Name	Description
request	`DetectIntentRequest` The request object containing all of the parameters for the API call.

Returns

Type	Description
DetectIntentResponse

detectIntent(SessionName session, QueryInput queryInput)

public final DetectIntentResponse detectIntent(SessionName session, QueryInput queryInput)

Note: Always use agent versions for production traffic. See Versions and environments.

Sample code:


 // This snippet has been automatically generated for illustrative purposes only.
 // It may require modifications to work in your environment.
 try (SessionsClient sessionsClient = SessionsClient.create()) {
   SessionName session = SessionName.ofProjectSessionName("[PROJECT]", "[SESSION]");
   QueryInput queryInput = QueryInput.newBuilder().build();
   DetectIntentResponse response = sessionsClient.detectIntent(session, queryInput);
 }

Parameters

Name Description

session

SessionName

Required. The name of the session this query is sent to. Supported formats: - projects/<Project ID>/agent/sessions/<Session ID>, - projects/<Project ID>/locations/<Location ID>/agent/sessions/<Session ID>, -projects/<Project ID>/agent/environments/<Environment ID>/users/<User ID>/sessions/<Session ID>, - projects/<Project ID>/locations/<Location ID>/agent/environments/<Environment ID>/users/<User ID>/sessions/<Session ID>,

If Location ID is not specified we assume default 'us' location. If Environment IDis not specified, we assume default 'draft' environment (Environment IDmight be referred to as environment name at some places). IfUser IDis not specified, we are using "-". It's up to the API caller to choose an appropriateSession ID and User Id. They can be a random number or some type of user and session identifiers (preferably hashed). The length of theSession ID and User ID` must not exceed 36 characters. For more information, see the API interactions guide.
