Scala example source code file (t2127.scala)

This example Scala source code file (t2127.scala) is included in the DevDaily.com "Java Source Code Warehouse" project. The intent of this project is to help you "Learn Java by Example" TM.

Java - Scala tags/keywords

access, array, array, bar, bar, illegal, int, int, test, test

The Scala t2127.scala source code

// Seems to be fixed in trunk

// As discussed here: http://www.nabble.com/Companion-object-constructor-visibility-td24342096.html

//Simplified example:

    class Test private (val value : Int)

    abstract class Bar(val ctor : (Int) => Test)

    object Test extends Bar(new Test(_)) { //<--- ILLEGAL ACCESS
      def main(args: Array[String]){}
    }

//however the following is legal:
/*
    class Foo private (val value : Int)

    abstract class Bar{

        var ctor : (Int) => Foo

    }

    object Foo extends Bar{

        ctor = new Foo(_) //<--- Legal access

    }

The constructor invocation of Bar is done within the scope of object Foo's constructor, and therefor the private constructor of Foo should be visible and accessible.
