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.

Hide Inherited Public Properties
Show Inherited Public PropertiescompatibilityErrorFunction:Function [read-write]
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.
public static function get compatibilityErrorFunction():Function
public function set compatibilityErrorFunction(value:Function):void
| compatibilityVersion | property |
compatibilityVersion:uint [read-write]
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.
public static function get compatibilityVersion():uint
public function set compatibilityVersion(value:uint):void
| compatibilityVersionString | property |
compatibilityVersionString:String [read-write]
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.
public static function get compatibilityVersionString():String
public function set compatibilityVersionString(value:String):void
| CURRENT_VERSION | Constant |
public static const CURRENT_VERSION:uint = 0x03000000
The current released version of the Flex SDK, encoded as a uint.
| VERSION_2_0 | Constant |
public static const VERSION_2_0:uint = 0x02000000
The compatibilityVersion value of Flex 2.0,
encoded numerically as a uint.
Code can compare this constant against
the compatibilityVersion
to implement version-specific behavior.
| VERSION_2_0_1 | Constant |
public static const VERSION_2_0_1:uint = 0x02000001
The compatibilityVersion value of Flex 2.0.1,
encoded numerically as a uint.
Code can compare this constant against
the compatibilityVersion
to implement version-specific behavior.
| VERSION_3_0 | Constant |
public static const VERSION_3_0:uint = 0x03000000
The compatibilityVersion value of Flex 3.0,
encoded numerically as a uint.
Code can compare this constant against
the compatibilityVersion
to implement version-specific behavior.
| VERSION_ALREADY_READ | Constant |
public static const VERSION_ALREADY_READ:String = "versionAlreadyRead"
A String passed as a parameter
to the compatibilityErrorFunction() method
if the compatibility version has already been read.
| VERSION_ALREADY_SET | Constant |
public static const VERSION_ALREADY_SET:String = "versionAlreadySet"
A String passed as a parameter
to the compatibilityErrorFunction() method
if the compatibility version has already been set.
