scala - Type upper bounds and inheritance -


Suppose we have a class pair and some heritage tree: 

  Class pair [T & LT: Comparative [T]] (R: T, T: T) {Df size relabations = R. Copretto (T)} Seal class person (val significance: IT) in comparative [person] {Override DRF Comparison (o: person): int = ??? } Student student in class (10) provides class teacher (50)

How to modify the uppercase to be able to create a couple [student] now?

(original) (original) (new student, new student) / * Student does not correspond to comparative * /
Maybe it helps: 

  val notixed = new pair (new student, (new student) .asInstanceOf [person])

I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
