UIDUtil.createUID() method.
Note: If you have a dynamic object that has no [Bindable] properties
(which force the object to implement the IUID interface), Flex adds an
mx_internal_uid property that contains a UID to the object.
To avoid having this field
in your dynamic object, make it [Bindable], implement the IUID interface
in the object class, or set a property with a value.

createUID | () | 메서드 |
public static function createUID():String| 언어 버전: | ActionScript 3.0 |
| 제품 버전: | Flex 3 |
| 런타임 버전: | Flash Player 9, AIR 1.1 |
Generates a UID (unique identifier) based on ActionScript's pseudo-random number generator and the current time.
The UID has the form
"XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX"
where X is a hexadecimal digit (0-9, A-F).
This UID will not be truly globally unique; but it is the best we can do without player support for UID generation.
반환값String — The newly-generated UID.

fromByteArray | () | 메서드 |
public static function fromByteArray(ba:ByteArray):String| 언어 버전: | ActionScript 3.0 |
| 제품 버전: | Flex 3 |
| 런타임 버전: | Flash Player 9, AIR 1.1 |
Converts a 128-bit UID encoded as a ByteArray to a String representation. The format matches that generated by createUID. If a suitable ByteArray is not provided, null is returned.
매개 변수
ba:ByteArray — ByteArray 16 bytes in length representing a 128-bit UID.
|
String — String representation of the UID, or null if an invalid
ByteArray is provided.
|
getUID | () | 메서드 |
public static function getUID(item:Object):String| 언어 버전: | ActionScript 3.0 |
| 제품 버전: | Flex 3 |
| 런타임 버전: | Flash Player 9, AIR 1.1 |
Returns the UID (unique identifier) for the specified object. If the specified object doesn't have an UID then the method assigns one to it. If a map is specified this method will use the map to construct the UID. As a special case, if the item passed in is null, this method returns a null UID.
매개 변수
item:Object — Object that we need to find the UID for.
|
String — The UID that was either found or generated.
|
isUID | () | 메서드 |
public static function isUID(uid:String):Boolean| 언어 버전: | ActionScript 3.0 |
| 제품 버전: | Flex 3 |
| 런타임 버전: | Flash Player 9, AIR 1.1 |
A utility method to check whether a String value represents a correctly formatted UID value. UID values are expected to be in the format generated by createUID(), implying that only capitalized A-F characters in addition to 0-9 digits are supported.
매개 변수
uid:String — The value to test whether it is formatted as a UID.
|
Boolean — Returns true if the value is formatted as a UID.
|
toByteArray | () | 메서드 |
public static function toByteArray(uid:String):ByteArray| 언어 버전: | ActionScript 3.0 |
| 제품 버전: | Flex 3 |
| 런타임 버전: | Flash Player 9, AIR 1.1 |
Converts a UID formatted String to a ByteArray. The UID must be in the format generated by createUID, otherwise null is returned.
매개 변수
uid:String — representing a 128-bit UID
|
ByteArray — ByteArray 16 bytes in length representing the 128-bits of the
UID or null if the uid could not be converted.
