Protected Members of Other Instances in Scala
- by Masterofpsi
I just ran into a difficulty while learning Scala. I have an inheritance hierarchy that is essentially equivalent to this:
class A {
protected def myMethod() = println("myMethod() from A")
}
class B extends A {
def invokeMyMethod(a: A) = a.myMethod()
}
But trying to compile this sample, I get the error "test.scala:7: error: method myMethod cannot be accessed in A".
Coming from Java, my understanding is that protected members should be accessible at any point from a derived class, and nowhere have I seen anything that tells me that protected members in Scala are limited by instance. Does anyone have an explanation for this?
