How to expose a constructor variable(sic!) as read-only?
- by Malax
Hi StackOverflow!
I have this rather simple question about Scala. Given that i have to following class definition:
class Foo(var bar: Int)
The code which is able to construct an instance of Foo must be able to pass the initial value for bar. But if I define bar as var the User is also able to change its value at runtime which is not what I want. The User should only be able to read bar. bar itself is modified internally so a val is not an option.
I think I might be getting an answer very soon as this question is so simple. :-)
Cheers,
Malax
