trait Application

[source: scala/Application.scala]

trait Application
extends AnyRef

The Application class can be used to quickly turn objects into executable programs. Here is an example:

  object Main extends Application {
    Console.println("Hello World!")
  }
  

Here, object Main inherits the main method of Application. The body of the Main object defines the main program. This technique does not work if the main program depends on command-line arguments (which are not accessible with the technique presented here).

It is possible to time the execution of objects that inherit from class Application by setting the global scala.time property. Here is an example for benchmarking object Main:

  java -Dscala.time Main
