Class type required but T found

Question

I can\'t create an actor for some reason (here is a simple version of my class hierarchy):

abstract class Class1[T <: Class2[_]: ClassTag] extends Actor {         


        

Answer 1

I think this is because of JVM restriction also known as "type erasure". http://docs.oracle.com/javase/tutorial/java/generics/erasure.html

also see "Cannot Create Instances of Type Parameters" at http://docs.oracle.com/javase/tutorial/java/generics/restrictions.html

By the way C# allows you to write:

new T()

when you define a restriction

where T: new()

but unfortunately constructor must be parameterless
