Question

I have one vector instance and I’m exporting swf with Flash Player 10/10.1.

I want initialise it with a parametric type. I tried as follow:

var someType:Class = MyCustomClass;
var v:Vector.<someType> = new Vector.<someType>();

But it doesn’t work!!
There is a way to do this?

I hope question is clear 🙂

Thanks in advance!

Answer 1

someType is the instance of the class type; whereas Vector is a container of that type.

This should be:

var v:Vector.<MyCustomClass> = new Vector.<MyCustomClass>();

Otherwise, I’ve noticed Haxe would compile this as:

var v:Vector.<Object> = new Vector.<Object>();

Flash polymorphism is lacking, if you had class A and class B, and attempted to push them to a vector of type Class you would receive an error:

Example

package
{
    import flash.display.Sprite;

    public class test extends Sprite
    {
        public function test()
        {
            var v:Vector.<Class> = new Vector.<Class>();

            var a:A = new A();
            var b:B = new B();

            v.push(a);
            v.push(b);
        }
    }
}

Error:

TypeError: Error #1034: Type Coercion failed: cannot convert A@43a2ff1 to Class.
