Widget inheritance calling question

Widget inheritance calling question

Hi,

      I am developing a plugin using jquery ui widget.  I have class (or widget) a -> class b -> class c.  In other words, b extend a, and c extend b.  I know that, for example, in class (or widget) c,

myFunc: function() {
     this._super();
}

it will execute myFunc in b. 

Let's say if I also have myFunc in class a,  how can I call it in class c, without execute myFunc in class b?

In other words, in class c,

myFunc : function() {
     //how can I execute myFunc in class a, but I don't want myFunc in class b being executed.
}
