如何从cakephp 3中的行为访问调用者模型？

I need caller model in my behavior to find and save data. How can I do something like this.

class MyBehavior extends Behavior {
    public function func() {
        $entities = $this->find()->all();
    }

The table instance a behavior is attached to, is being passed to the constructor, and assigned to the $_table property.

public function func() {
    $entities = $this->_table->find()->all();
}
