Description
I want a case class where the access to its constructors (including companion.apply) is private, or to not have the synthetic constructor created.
case class Foo private(x: Int)
object Foo {
// apply not public
def make(x: Int): Option[Foo] = ??? // public constructor
}Adding or overriding Foo.apply causes "error: method apply is defined twice".
The only workaround I could find is to not use a case class; use a regular class, and define your own val, apply, unapply, toString, canEqual, equals, hashCode; seems unfortunate.
