源码Source io/agentscope/core/agent/Event.java:57–219

事件，描述执行过程中的事件。位于 io.agentscope.core.agent 包。核心成员包括 withSource、getType、getMessage、isLast、getSource、getMessageId。

An event emitted during streaming agent execution.

Events provide a structured way to observe agent execution, with clear type identification and completion status for each message.

Example usage:

`agent.stream(userMsg, options)
.subscribe(event -> {
switch (event.getType()) {
case REASONING -> {
if (event.isLast()) {
System.out.println("✓ Reasoning complete");
} else {
System.out.print("..."); // Progress indicator
}
}
case TOOL_RESULT -> {
System.out.println("Tool: " + event.getMessage().getTextContent());
}
}
});
`
