Calling a Subclass Method from a Superclass

Let’s use the following example to illustraite my dillema:


package {
 
  public class Superclass
  {
    public var $thisVar:String = undefined;
 
    function Superclass(){
       $thisVar = 'woot';
    }
  }
}
 
package {
 
  public class Subclass extends Superclass
  {
    function Subclass(){
       trace($thisVar);
    }
  }
}

Given the above example, the following code when used inside the Superclass would cause a Stack Overflow:

subclass:Subclass = new Subclass();

Because of this, I can’t really use any of the subclass methods.

Since I’m somewhat new to proper OOP practices, I’m also wondering whether or not this is a good idea. The current goal of the relationship between these two classes is:

  • extending the subclass should allow me to use $variables defined in the superclass on subclass methods.
  • by instantiating the subclass i can call some of the subclass functions from inside my superclass

Since I could probably set this up in a more efficient manner, any OOP advice here would be appreciated.
