This class controls the backward-compatibility of the framework. With every new release, some aspects of the framework such as behaviors, styles, and default settings, are changed which can affect your application. By setting the compatibilityVersion property, the behavior can be changed to match previous releases. This is a 'global' flag; you cannot apply one version to one component or group of components and a different version to another component or group of components.

Property Detail
compatibilityErrorFunctionproperty
compatibilityErrorFunction:Function

Language Version : ActionScript 3.0
Product Version : Flex 3
Runtime Versions : Flash Player 9, AIR 1.1

A function that gets called when the compatibility version is set more than once, or set after it has been read. If this function is not set, the SDK throws an error. If set, File calls this function, but it is up to the developer to decide how to handle the call. This function will also be called if the function is set more than once. The function takes two parameters: the first is a uint which is the version that was attempted to be set; the second is a string that is the reason it failed, either VERSION_ALREADY_SET or VERSION_ALREADY_READ.


Implementation
    public static function get compatibilityErrorFunction():Function
    public static function set compatibilityErrorFunction(value:Function):void
compatibilityVersionproperty 
compatibilityVersion:uint

Language Version : ActionScript 3.0
Product Version : Flex 3
Runtime Versions : Flash Player 9, AIR 1.1

The current version that the framework maintains compatibility for. This defaults to CURRENT_VERSION. It can be changed only once; changing it a second time results in a call to the compatibilityErrorFunction() method if it exists, or results in a runtime error. Changing it after the compatibilityVersion property has been read results in an error because code that is dependent on the version has already run. There are no notifications; the assumption is that this is set only once, and this it is set early enough that no code that depends on it has run yet.

The default value is FlexVersion.CURRENT_VERSION.


Implementation
    public static function get compatibilityVersion():uint
    public static function set compatibilityVersion(value:uint):void
compatibilityVersionStringproperty 
compatibilityVersionString:String

Language Version : ActionScript 3.0
Product Version : Flex 3
Runtime Versions : Flash Player 9, AIR 1.1

The compatibility version, as a string of the form "X.X.X". This is a pass-through to the compatibilityVersion property, which converts the number to and from a more human-readable String version.


Implementation
    public static function get compatibilityVersionString():String
    public static function set compatibilityVersionString(value:String):void
