Special case for @var $this

I'm working with Yii framework and they implement templates inside controller class. So in templates I can access all controller data via $this.
How I can say to PhpStorm about it - that this current file included inside specific class?
Now i'm using phpDoc construction /** @var $this SomeController */
It's work well except access to protected members. So in this example

a.php:
<?
class A {
  protected $test;

  public function test()
  {
    include("b.php");
  }
}
?>
 
b.php:
<?php
  /** @var A $this */
  echo $this->test;
?>
