Message is one unit of communication between client and server. It is associated with a context and optionally a task. Since the server is responsible for the context definition, it must always provide a context_id in its messages. The client can optionally provide the context_id if it knows the context to associate the message to. Similarly for task_id, except the server decides if a task is created and whether to include the task_id.
This is the Java data model class that specifies how to parse/serialize into the JSON that is transmitted over HTTP when working with the Discovery Engine API. For a detailed explanation see: https://developers.google.com/api-client-library/java/google-http-java-client/json
