flex 常用元标签讲解
Flex
引入了元数据标签的概念，大多数人都使用过的
[Bindable]
标签便是其中的
meta tag
之一，它在代码中的作用就是向编译器提供如何编译程序的信息。实际上，这些标签并没有被编译到生成的
SWF
文件中，而只是告诉编译器如何生成
SWF
文件。

16种
meta
的使用，简单如下表所示。
Tag
Description
[ArrayElementType]
Defines the allowed data type of each element of an Array.
[Bindable]
Identifies a property that you can use as the source of a data
binding expression.
[DefaultProperty]
Defines the name of the default property of the component when you
use the component in an MXML file.
[Deprecated]
Marks a class or class element as deprecated so that the compiler
can recognize it and issue a warning when the element is used in an
application.
[Effect]
Defines the MXML property name for the effect.
[Embed]
Imports JPEG, GIF, PNG, SVG, and SWF files at compile time. Also
imports image assets from SWC files.
[Event]
Defines the MXML property for an event and the data type of the
event object that a component emits.
[Exclude]
Omits the class element from the Flex Builder tag inspector. The
syntax is as follows:[Exclude(name="label",
kind="property")]
[ExcludeClass]
Omits the class from the Flex Builder tag inspector. This is
equivalent to the @private tag in ASDoc when applied to a class.

Identifies the filename for the icon that represents the component
in the Insert bar of Adobe Flex Builder.
[Inspectable]
Defines an attribute exposed to component users in the attribute
hints and Tag inspector of Flex Builder. Also limits allowable values of the

IDeferredInstance.
