Flex metadata tags

You insert metadata tags into your MXML and ActionScript files to provide information to the Flex compiler. Metadata tags do not get compiled into executable code, but provide information to control how portions of your code get compiled.

官方公開的metadata tags

[ArrayElementType]
Defines the allowed data type of each element of an Array. For more information, see ArrayElementType metadata tag.


[Bindable]
Identifies a property that you can use as the source of a data binding expression. For more information, see Bindable metadata tag.


[DefaultProperty]
Defines the name of the default property of the component when you use the component in an MXML file. For more information, see DefaultProperty metadata tag.


[Effect]
Defines the MXML property name for the effect. For more information, see Effect metadata tag.


[Embed]
Imports JPEG, GIF, PNG, SVG, and SWF files at compile time. Also imports image assets from SWC files. This is functionally equivalent to the MXML @Embed syntax, as described in Embedding Assets in Flex 2 Developer's Guide.

Specifies the allowed data type of a property of type IDeferredInstance. For more information, see InstanceType metadata tag.


[NonCommittingChangeEvent]
