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:

 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:

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 SessionsSettings to create(). For example:

To customize credentials:

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

To customize the endpoint:

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

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:

 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)

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:

 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. Format: projects/<Project ID>/agent/sessions/<Session ID>, or projects/<Project ID>/agent/environments/<Environment ID>/users/<User ID>/sessions/<Session ID>. If Environment ID is not specified, we assume default 'draft' environment (Environment ID might be referred to as environment name at some places). If User ID is not specified, we are using "-". It's up to the API caller to choose an appropriate Session ID and User Id. They can be a random number or some type of user and session identifiers (preferably hashed). The length of the Session ID and User ID must not exceed 36 characters. For more information, see the API interactions guide. Note: Always use agent versions for production traffic. See Versions and environments.
queryInput	QueryInput Required. The input specification. It can be set to: 1. an audio config which instructs the speech recognizer how to process the speech audio, 2. a conversational query in the form of text, or 3. an event that specifies which intent to trigger.

Returns

Type	Description
DetectIntentResponse
