Scala Language Scope Object private scope
Example
The most restrictive scope is "object-private" scope, which only allows that value to be accessed from the same instance of the object.
class FooClass {
private[this] val x = "foo"
def aFoo(otherFoo: FooClass) = {
otherFoo.x // <- This will not compile, accessing x outside the object instance
}
}
