[TYPO3-mvc] Check the request

[Dawid Pacholczyk]

I want to get an argument for my uri so I use
$this->request->getArgument('argument_name');

But when it isn`t set I receive error. Cool. Nothing wrong with that. But is
there some method tha I can use to check first if the argument exists ?
Cause I have same view with 2 states on one page and they depend on the
argument value so I need to check it on start but I can`t cause when it`s
not set I receive an error :(

Best regards,
Dawid Pacholczyk
