PLUGINS

Plugins provide ways the change the behavior of a component.

The baseclass is Kwf_Component_Plugin_Abstract. Additionally the plugin class must implement one of the plugin interfaces to do something useful.

To add a plugin to a component set it in getSettings-function like this:

$ret['plugins'] = array('My_Plugin_Component', 'My_Second_Plugin_Component');
