Title Body

I'm working on an automatic mapping framework built on top of Dozer. I won't go into specifics as it's not relevant to the question but in general it's supposed to allow easy transformation from class A to class B. I'd like to register the projections from a class's companion object. Below is a (simplified) example of how I want this to work, and a Specs test that assures that the projection is being registered properly. Unfortunately, this doesn't work. From what I can gather, this is because nothing initializes the A companion object. And indeed, if I call any method on the A object (like the commented-out hashCode call, the projection is being registered correctly. My question is - how can I cause the A object to be initialized automatically, as soon as the JVM starts? I don't mind extending a Trait or something, if necessary. Thanks. class A { var data: String = _ } class B { var data: String = _ } object A { projekt[A].to[B] } "dozer projektor" should { "transform a simple bean" in { // A.hashCode val a = new A a.data = "text" val b = a.-->[B] b.data must_== a.data } }
