public class FlowException
extends OpenException

Base exception for the opencode-base-flow module. opencode-base-flow 模块的异常基类。

All flow-related exceptions extend this class. Carries a stable errorCode (see FlowErrorCode) that callers may switch on programmatically; the human-readable message is intended for logs and operator diagnostics.

所有流程相关异常均继承本类。携带稳定的 errorCode （见 FlowErrorCode），调用方可基于其做编程式分支；人类可读的 message 仅用于日志与运维诊断。

Inherits from OpenException which itself extends RuntimeException - all flow exceptions are unchecked.

继承自 OpenException，其本身继承 RuntimeException —— 所有流程异常都是非受检异常。

Since:

JDK 25, opencode-base-flow V1.0.5
