所有已实现的接口:

ChatMessage

public class UserMessage
extends Object
implements ChatMessage

Represents a message from a user, typically an end user of the application.
Depending on the supported modalities (text, image, audio, video, etc.) of the model, user messages can contain either a single text (a String) or multiple Contents, which can be either TextContent or ImageContent. In the future, the list of Content types will expand to allow for more modalities (e.g. audio, video, etc.).
Optionally, user message can contain a name of the user. Be aware that not all models support names in UserMessage.
