trait NewHook extends (App) => Hook

Create a new hook for the given App. NewHooks are service-loaded.

To use, extend the NewHook trait and implement an apply method which returns a Hook implementation, e.g.,

Add the Hook as a service-loaded class in /META-INF/services/com.twitter.server.NewHook

class MyHook extends NewHook {
  def apply(app: App) = new Hook {

    override def premain(): Unit = ???

    override def onExit(): Unit = ???
  }
}
