      Description

      Unused parameters are misleading. Whatever the value passed to such parameters is, the behavior will be the same.

      Noncompliant Code Example

      function doSomething(a:int, b:int):void      // "b" is unused
      {
        compute(a);
      }
      

      Compliant Solution

      function doSomething(a:int):void
      {
        compute(a);
      }
      

      Exceptions

      The following cases are ignored

      • event handlers.
      • overriding methods.
      • all methods in classes implementing one or more interfaces.
      • methods which are empty or where the body consists of a single comment or a single throw statement (i.e. where the intention is apparently to simulate an abstract class).
      override function doSomething(a:int):void {    // ignored
        compute(a);
      }
      
      ...
      
      class AbstractSomething {
        public function doSomething(a:int) {  // ignored
          throw new IllegalOperationError("doSomething() is abstract");
        }
      
      ...
      
      interface I {
        function action(a:int, b:int);
      }
      
      class C extends I {
        function action(a:int, b:int) { // ignored
          return doSomethignWith(a);
        }
      }
      
      function clickHandler(event:MouseEvent):void { // ignored
         trace("click");
      }
