Class SessionsClient (2.33.0)

A service used for session interactions.

For more information, see the API interactions guide.

Equality

Instances of this class created via copy-construction or copy-assignment always compare equal. Instances created with equal std::shared_ptr<*Connection> objects compare equal. Objects that compare equal share the same underlying resources.

Performance

Creating a new instance of this class is a relatively expensive operation, new objects establish new connections to the service. In contrast, copy-construction, move-construction, and the corresponding assignment operations are relatively efficient as the copies share all underlying resources.

Thread Safety

Concurrent access to different instances of this class, even if they compare equal, is guaranteed to work. Two or more threads operating on the same instance of this class is not guaranteed to work. Since copy-construction and move-construction is a relatively efficient operation, consider using such a copy when using this class from multiple threads.

Functions

DetectIntent(std::string const &, google::cloud::dialogflow::v2::QueryInput const &, Options)

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][google.cloud.dialogflow.v2.Participants.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.

Parameters
Name	Description
`session`	`std::string const &` Required. The name of the session this query is sent to. Format: `projects/<ProjectID>/agent/sessions/<Session ID>`, or `projects/<ProjectID>/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.
`query_input`	`google::cloud::dialogflow::v2::QueryInput const &` Required. The input specification. It can be set to: an audio config which instructs the speech recognizer how to process the speech audio, a conversational query in the form of text, or an event that specifies which intent to trigger.
`opts`	`Options` Optional. Override the class-level options, such as retry and backoff policies.

Returns
Type	Description
`StatusOr< google::cloud::dialogflow::v2::DetectIntentResponse >`	the result of the RPC. The response message type (google.cloud.dialogflow.v2.DetectIntentResponse) is mapped to a C++ class using the Protobuf mapping rules. If the request fails, the `StatusOr` contains the error details.

DetectIntent(google::cloud::dialogflow::v2::DetectIntentRequest const &, Options)

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.

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

Parameters
Name	Description
`request`	`google::cloud::dialogflow::v2::DetectIntentRequest const &` Unary RPCs, such as the one wrapped by this function, receive a single `request` proto message which includes all the inputs for the RPC. In this case, the proto message is a google.cloud.dialogflow.v2.DetectIntentRequest. Proto messages are converted to C++ classes by Protobuf, using the Protobuf mapping rules.
`opts`	`Options` Optional. Override the class-level options, such as retry and backoff policies.

Returns
Type	Description
`StatusOr< google::cloud::dialogflow::v2::DetectIntentResponse >`	the result of the RPC. The response message type (google.cloud.dialogflow.v2.DetectIntentResponse) is mapped to a C++ class using the Protobuf mapping rules. If the request fails, the `StatusOr` contains the error details.

AsyncStreamingDetectIntent(Options)

Processes a natural language query in audio format in a streaming fashion and returns structured, actionable data as a result.

This method is only available via the gRPC API (not REST).

If you might use Agent Assist or other CCAI products now or in the future, consider using [StreamingAnalyzeContent][google.cloud.dialogflow.v2.Participants.StreamingAnalyzeContent] instead of StreamingDetectIntent. StreamingAnalyzeContent has additional functionality for Agent Assist and other CCAI products.

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

Parameter
Name	Description
`opts`	`Options` Optional. Override the class-level options, such as retry and backoff policies.

Returns

Type Description

std::unique_ptr<::google::cloud::AsyncStreamingReadWriteRpc< google::cloud::dialogflow::v2::StreamingDetectIntentRequest, google::cloud::dialogflow::v2::StreamingDetectIntentResponse > >

An object representing the bidirectional streaming RPC. Applications can send multiple request messages and receive multiple response messages through this API. Bidirectional streaming RPCs can impose restrictions on the sequence of request and response messages. Please consult the service documentation for details. The request message type (google.cloud.dialogflow.v2.StreamingDetectIntentRequest) and response messages (google.cloud.dialogflow.v2.StreamingDetectIntentResponse) are mapped to C++ classes using the Protobuf mapping rules.

ListLocations(google::cloud::location::ListLocationsRequest, Options)

Lists information about the supported locations for this service.

Parameters
Name	Description
`request`	`google::cloud::location::ListLocationsRequest` Unary RPCs, such as the one wrapped by this function, receive a single `request` proto message which includes all the inputs for the RPC. In this case, the proto message is a google.cloud.location.ListLocationsRequest. Proto messages are converted to C++ classes by Protobuf, using the Protobuf mapping rules.
`opts`	`Options` Optional. Override the class-level options, such as retry and backoff policies.

Returns

Type Description

StreamRange< google::cloud::location::Location >

a StreamRange to iterate of the results. See the documentation of this type for details. In brief, this class has begin() and end() member functions returning a iterator class meeting the input iterator requirements. The value type for this iterator is a StatusOr as the iteration may fail even after some values are retrieved successfully, for example, if there is a network disconnect. An empty set of results does not indicate an error, it indicates that there are no resources meeting the request criteria. On a successful iteration the StatusOr<T> contains elements of type google.cloud.location.Location, or rather, the C++ class generated by Protobuf from that type. Please consult the Protobuf documentation for details on the Protobuf mapping rules.

GetLocation(google::cloud::location::GetLocationRequest const &, Options)

Gets information about a location.

Parameters
Name	Description
`request`	`google::cloud::location::GetLocationRequest const &` Unary RPCs, such as the one wrapped by this function, receive a single `request` proto message which includes all the inputs for the RPC. In this case, the proto message is a google.cloud.location.GetLocationRequest. Proto messages are converted to C++ classes by Protobuf, using the Protobuf mapping rules.
`opts`	`Options` Optional. Override the class-level options, such as retry and backoff policies.

Returns
Type	Description
`StatusOr< google::cloud::location::Location >`	the result of the RPC. The response message type (google.cloud.location.Location) is mapped to a C++ class using the Protobuf mapping rules. If the request fails, the `StatusOr` contains the error details.

ListOperations(std::string const &, std::string const &, Options)
