== Why is this an issue?

include::../description.adoc[]

=== Exceptions

The rule ignores the following cases:

* event handlers.
* overriding methods.
* all methods in classes implementing one or more interfaces.
* empty methods or methods where the body consists of a single comment or a single `throw` statement (i.e. where the intention is 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");

=== Code examples

==== Noncompliant code example

[source,flex,diff-id=1,diff-type=noncompliant]
----
function doSomething(a:int, b:int):void      // "b" is unused
{
  compute(a);
}
----

==== Compliant solution

[source,flex,diff-id=1,diff-type=compliant]
----
function doSomething(a:int):void
{
  compute(a);
}
