Is scala's cake pattern possible with parametrized components?
- by Nicolas
Parametrized components work well with the cake pattern as long as you are only interested in a unique component for each typed component's, example:
trait AComponent[T] {
val a:A[T]
class A[T](implicit mf:Manifest[T]) {
println(mf)
}
}
class App extends AComponent[Int] {
val a = new A[Int]()
}
new App
Now my application requires me to inject an A[Int] and an A[String], obviously scala's type system doesn't allow me to extends AComponent twice. What is the common practice in this situation ?
