  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      // "b" is unused
{
  compute(a);
}


Exceptions
The following cases are ignored

  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);
  }
}
