MessageContent
@JsonDeserialize(using = MessageContentDeserializer.class) @JsonSerialize(using = MessageContentSerializer.class) public sealed interface MessageContent permits MessageContent.Text, MessageContent.Blocksio/agentscope/core/agui/model/MessageContent.java:45–72定义消息内容契约的接口。位于 io.agentscope.core.agui.model 包。
Type-safe union representing the content field of an AG-UI message.
In the AG-UI protocol, message content can be either a plain string or an
array of structured InputContent parts. This sealed interface models
that union without resorting to Object, providing compile-time type
safety and exhaustive pattern matching.
JSON forms:
-
Text→ JSON string:"Hello" -
Blocks→ JSON array:[{"type":"text","text":"Hi"},{"type":"image",...}]
Custom Jackson serialization/deserialization handles the non-object JSON
shape (scalar vs. array) via MessageContentDeserializer and
MessageContentSerializer.
