as3 - figure out the variable type from an empty variable

Is it possible to figure out the variable type when the variable isn't instantiated?

Example of what I'm trying to accomplish:

var foo:ExampleOne;
var bar:ExampleTwo;

var arr:Array = [foo, bar];

for each(var myVar:Object in arr开发者_JAVA技巧)
{
    myClass = new getDefinitionByName( getQualifiedClassName( myVar ) ) // doesn't work
}

No, because the variables are a reference to objects that are not created in the vm until you create them using the "new" keyword. So until you do this, the references (foo/bar etc) will always be null no matter what operation you're running on them.

I don't know what do you want to do, but you could may be use describeType :

package
{
    import flash.display.Sprite;
    import flash.text.TextField;
    import flash.utils.ByteArray;
    import flash.utils.describeType;
    import flash.utils.getDefinitionByName;


    public class TestTextfield extends Sprite
    {
        public var foo:TextField;
        public var bar:ByteArray;

        public function TestTextfield()
        {
            var arr:Array = ["foo", "bar"];

            for each(var myVar:String in arr)
            {
                var varClass : String = describeType(this)..variable.(@name == myVar).@type.toString();
                var myClass : * = new (getDefinitionByName(varClass) as Class)
            }
        }

    }
}

Try to use the "className" property.

It should return "TextInput", "Button", etc... depending the case

for each (var item:* in myArray)
{
    if(item.hasProperty('className'))
    {
        trace("item ["+i+"] is :" + item['className']);
    }
}

---

maybe you want to do something like this ?

var a:Class = MyClassA; //put a reference to a Class object into 'a' variable
var b:Class = MyClassB;

var classes:Array = [a,b];

for each(var classObj:Class in classes){
  var objInstance : * = new classObj()
}
