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");
}
