I'm not sure I understand the question. The TriggerData.getArguments()
will return an array of strings. There's no limit to the number of
strings. These strings are the arguments that you define in your EXECUTE
PROCEDURE xxx(arg1, arg2, arg3). In your case you can do

String[] args = td.getArguments();
if(td[0].equals("valor")) { ... }

But perhaps you're after something completely different?
