Model the caller of a function

[Christian Banse]

Is it possible to model in MARK the caller of a function/operation, i.e. to restrict that a certain function should only be called by a specific other function or better just with a certain class?

[Florian Wendland]

An example:

class B {
  fun myFunc() {
    obj.call()
  }
}

Is it possible to restrict calling obj.call() only from within B.myFunc()?
