Why would you need such a check?
You want to ensure that the class that is using your trait obeys a certain
interface, right?
More specifically, you need it to implement a number of methods of an
interface, correct?
So, why not asking for it explicitly?
<?php
trait InnerIteratorImpl {
abstract function next();
public function apply() {
do somthing with $this->next() ...
}
}
?>
Does that what you want it to do?
Best regards
Stefan
