It seems like getChildren() must be provided by classes using this trait. How about adding it as abstract method to this trait?
                                                                                                

                    
                                            

                            

                            

                                
                                    
                                
                            


                            
This check looks for methods that are used by a trait but not required by it.


To illustrate, let’s look at the following code example


trait Idable {
    public function equalIds(Idable $other) {
        return $this->getId() === $other->getId();
    }
}





The trait Idable provides a method equalsId that in turn relies on the
method getId(). If this method does not exist on a class mixing in this
trait, the method will fail.


Adding the getId() as an abstract method to the trait will make sure it
is available.
