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. Loading history...
