本文整理了Java中org.springframework.webflow.execution.Event类的一些代码示例，展示了Event类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Event类的具体详情如下：
包路径：org.springframework.webflow.execution.Event
类名称：Event

Event介绍

[英]Signals the occurrence of something an active flow execution should respond to. Each event has a string id that provides a key for identifying what happened: e.g "coinInserted", or "pinDropped". Events may have attributes that provide arbitrary payload data, e.g. "coin.amount=25", or "pinDropSpeed=25ms".

As an example, a "submit" event might signal that a Submit button was pressed in a web browser. A "success" event might signal an action executed successfully. A "finish" event might signal a subflow ended normally.

Why is this not an interface? A specific design choice. An event is not a strategy that defines a generic type or role--it is essentially an immutable value object. It is expected that specializations of this base class be "Events" and not part of some other inheritance hierarchy.
[中]指示活动流执行应响应的事件的发生。每个事件都有一个字符串id，该id提供了一个用于识别发生了什么的键：例如“coinserted”或“pindrop”。事件可能具有提供任意有效负载数据的属性，例如“coin.amount=25”或“pinDropSpeed=25ms”。
例如，“提交”事件可能表示在web浏览器中按下了提交按钮。“成功”事件可能表示操作已成功执行。“完成”事件可能表示亚流正常结束。
为什么这不是一个接口？具体的设计选择。事件不是定义泛型类型或角色的策略——它本质上是一个不可变的值对象。这个基类的专门化应该是“事件”，而不是其他继承层次结构的一部分。
