trait Logging extends AnyRef

A scala-friendly Logging trait which:

  • lazily provides a logger named according to the class in which the trait is mixed
  • convenience methods to proxy calls to the lazily provided logger. These methods are explicitly call-by-name as they are mainly intended for use from Scala.
class MyClass extends Logging {
  ...
  def foo: String = {
    info("In foo method")
    "Hello, world!"
  }
}
