Scala Modifiers and Type parametrization

Question

I\'m creating a memoization class.

Each class memoizes a function type and has the following definition:

 class MemoizedFunction1[-T1, +R](f: T1 => R)         


        

Answer 1

Programming in Scala touches on this topic in Section 19.7 Object private data: "object private members can be accessed only from within the object in which they are defined. It turns out that accesses to variables from the same object in which they are defined do not cause problems with variance."
