ParameterNumber check after an @Override

Hi everyone,

I am using a rule for the parameter number. Nevertheless, I sometimes 
have to override some methods (in Swing, for example). Those methods may 
have more parameters than what the rule is configured to allow. I would 
like this rule to be ignored when applied to an overridden method.

Does it make sense? If so, how may I do this? I have looked at 
suppression filters, but they work either with a configuration file 
(that you need to maintain) or keywords in the code (which makes you add 
to your files, text for a specific tool).

Trying to write a custom filter, for what I have understood, it seems to 
allow reaching text and the lines of it, but you do not have access to a 
structure as you have in a check. I was worried that using some kind of 
text regexp on a line would be brittle.

Thus I have written a custom check, inheriting from ParameterNumberCheck 
class. This works. But I would have to maintain it in my project locally 
for future checkstyle releases.

Thus, is there another better way to do it?
Do you think this request should become a feature request?

Thanks.

R.
