TYPO3 Core

The structure of the FinisherVariableProvider is very rigid and do not allow to iterate through all iterator variables. Since this class is used for the communication between finishers, there might be a use case when you need to iterate through all finisher variables, without knowing their ids.

The solution is to add a getter:

getObjects() {
return $this->objects;
}

Important keyword: API First

Also, I see no reason why this class should be final. Heck, not a single class in the sysext is final...
