[fw-general] Invoke Arg in Plugin

[Ian Warner]

Hi

Can I get at Parameters I have set within the front controller within a 
plugin?

ie in bootstrap

$controller->setControllerDirectory($controllers)
  ->throwExceptions(true)
  ->setParam('config', $config)
  ->setParam('db', $db)
  ->setParam('site_name', $site_name)
  ->setParam('translate', $translate)
  ->setParam('view', $view)
  ->registerPlugin(new Zend_Plugin_Auth())
  ->registerPlugin(new Zend_Plugin_Translation());

what i want to do in a plugin is:

$this->_config    = $this->getInvokeArg('config');

is this possible?

Cheers

Ian
