Interface method not implemented by class :(

Question

I'm getting an error for interface method
Interface method handleLogout in namespace  views.interfaces:IWiseMediator not implemented by class  views.mediators:RatingViewMediator.    RatingViewMediator.as 
package views.interfaces
    import flash.events.Event;
    public interface IWiseMediator
        function handleLogout(event:Event):void;
but I done this in RatingViewMediator
private function handleLogout(event:Event):void
            viewObject.clearFields();

interfaces are used to enforce a public 'interface' to the class. as a private method can only be accessed by the class itself, it doesn't make sense to include private methods in an interface.
