Class ConversationsClient (2.31.0)

Service for managing Conversations.

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

CreateConversation(std::string const &, google::cloud::dialogflow::v2::Conversation const &, Options)

Creates a new conversation.

Conversations are auto-completed after 24 hours.

Conversation Lifecycle: There are two stages during a conversation: Automated Agent Stage and Assist Stage.

For Automated Agent Stage, there will be a dialogflow agent responding to user queries.

For Assist Stage, there's no dialogflow agent responding to user queries. But we will provide suggestions which are generated from conversation.

If Conversation.conversation_profile is configured for a dialogflow agent, conversation will start from Automated Agent Stage, otherwise, it will start from Assist Stage. And during Automated Agent Stage, once an Intent with Intent.live_agent_handoff is triggered, conversation will transfer to Assist Stage.

Parameters
Name Description
parent std::string const &

Required. Resource identifier of the project creating the conversation. Format: projects/<ProjectID>/locations/<LocationID>.

conversation google::cloud::dialogflow::v2::Conversation const &

Required. The conversation to create.

opts Options

Optional. Override the class-level options, such as retry and backoff policies.

Returns
Type Description
StatusOr< google::cloud::dialogflow::v2::Conversation >

the result of the RPC. The response message type (google.cloud.dialogflow.v2.Conversation) is mapped to a C++ class using the Protobuf mapping rules. If the request fails, the StatusOr contains the error details.

Parameters
Name Description
request google::cloud::dialogflow::v2::CreateConversationRequest 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.CreateConversationRequest. 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::Conversation >

the result of the RPC. The response message type (google.cloud.dialogflow.v2.Conversation) is mapped to a C++ class using the Protobuf mapping rules. If the request fails, the StatusOr contains the error details.

ListConversations(std::string const &, Options)

Returns the list of all conversations in the specified project.

Parameters
Name Description
parent std::string const &

Required. The project from which to list all conversation. Format: projects/<ProjectID>/locations/<LocationID>.

opts Options

Optional. Override the class-level options, such as retry and backoff policies.

Returns
Type Description
StreamRange< google::cloud::dialogflow::v2::Conversation >
