* <pre>
* action class names or action configuration arrays. For example,

* </pre>
* Derived classes may override this method to declare external actions.
* ~~~
*
* Note, in order to inherit actions defined in the parent class, a child class needs to
* merge the parent actions with child actions using functions like array_merge().
* [[\Yii::createObject()]] will be invoked to create the requested action

*
* You may import actions from an action provider
* (such as a widget, see {@link CWidget::actions}), like the following:
* <pre>
* return array(
* ...other actions...
* // import actions declared in ProviderClass::actions()
* // the action IDs will be prefixed with 'pro.'

* 'action1'=>array(
* 'property1'=>'value1',
* ),
* 'action2'=>array(
* 'property2'=>'value2',
* ),
* ),
* )
* </pre>
* Derived classes may override this method to declare external actions.
*
* In the above, we differentiate action providers from other action
* declarations by the array keys. For action providers, the array keys
* must contain a dot. As a result, an action ID 'pro2.action1' will
* be resolved as the 'action1' action declared in the 'ProviderClass'.
