Scala: can't write setter without getter?
- by IttayD
This works:
class ButtonCountObserver {
private var cnt = 0 // private field
def count = cnt // reader method
def count_=(newCount: Int) = cnt = newCount // writer method
// ...
}
val b = new ButtonCountObserver
b.count = 0
But this doesn't
class ButtonCountObserver {
private var cnt = 0 // private field
def count_=(newCount: Int) = cnt = newCount // writer method
// ...
}
val b = new ButtonCountObserver
b.count = 0
I get: error: value count is not a member of ButtonCountObserver
Is it possible to create a setter (with the syntactic sugar) without a getter?
