AS3 - 如何獲得一個類的常量數組？

Question

static public const CONST_1 :String = "CONST_1"; 
static public const CONST_A :String = "CONST_A"; 

public var constantsArr :Array; 

是否有可能獲取類常量數組，而無需手動添加它們是這樣的：

constantsArr = [ CONST_1, CONST_A ]; 

Answer 1

使用的describeType它應該是可能的：

public class Constants 
{ 
    static public const CONST_1 :String = "CONST_1"; 
    static public const CONST_A :String = "CONST_A"; 
} 

var xmlList:XMLList = describeType(Constants).child("constant"); 

var constantsArray:Array = []; 
for each(var key:XML in xmlList) 
{ 
    constantsArray.push(key.attribute("name")); 
}
