在AS3类定义之前括号 [英] square bracket before class definition in as3

问题描述

我见过的类定义之前使用的嵌入标记，但我只看到基思使用这些。

I've seen the embed tag used before the class definition, but I just saw that Keith is using these..

[Event(name="select", type="flash.events.Event")]
[Event(name="close", type="flash.events.Event")]
[Event(name="resize", type="flash.events.Event")]
public class Window extends Component{

有人可以告诉我这是什么呢？

can someone tell me what this does?

推荐答案

大多数importantantly，Flex编译器使用它时，除preting MXML。但实际上它只是元数据，ASDocs和放大器;一些code完成的实现将用它向你展示了可用的事件，但多数民众赞成它。

Most importantantly, the Flex compiler uses it when interpreting MXML. But really its just metadata, ASDocs & some code completion implementations will use it to show you the available events, but thats about it.
