如何将类作为变量传递？

Question

有没有办法在ActionScript 3.0中作为变量传递一个类？

例如：

private var myType:* // not sure how to pass, it's a class which implements an interface 

myType = ClassA; // myType is now ClassA which extends Sprite; 
myType = ClassB; // myType is now ClassB which extends Sprite; 

Answer 1

private var myType:Class = ClassA 
var o:* = new myType(); 

ø现在是ClassA的
