what variable type is one that can be set multiple types of class?

Hi,
I have a method that can set a variable to various types of class depending on the outcome of a if statement.

But as its an unknown what class the variable will be set to before running the method I dont know what type I could set the variable too?


This is my code....

private var displayRender
        private function setdisplayRender() {
            if (recievedAddData.type == "swf") {
                displayRender = new swfDisplay(null, troot, ssModel);
            }else if (recievedAddData.type == "img") {              
                displayRender = new imgDisplay(null, troot, ssModel);
            }else if (recievedAddData.type == "flv") {              
                displayRender = new videoDisplay(null, troot, ssModel);
            }
        }

Basically what variable type Could I set displayRender to?


Thanks
Aidan

Ideally, you would set its type as a superclass of all alternatives, or an interface that they all implement.
