Reference documentation and code samples for the Dialogflow v3 API class Sessions.
A session represents an interaction with a user. You retrieve user input
and pass it to the
[DetectIntent][google.cloud.dialogflow.cx.v3.Sessions.DetectIntent] method to
determine user intent and respond.
public static void BindService(ServiceBinderBase serviceBinder, Sessions.SessionsBase serviceImpl)
Register service method with a service binder with or without implementation. Useful when customizing the service binding logic.
Note: this method is part of an experimental API that can change or be removed without any prior notice.
