•  trait ConfTyped extends AnyRef

  Trait that provides a DSL for creating a typed hierarchical configuration object.

  Trait that provides a DSL for creating a typed hierarchical configuration object.

  It provides access to two main abstractions: Conf and Prop

  Example:

  import za.co.absa.commons.config._
  
  object MyAppConfig extends ConfTyped {
  val confSource: java.util.Properties = ???
  
  override val rootPrefix = "com.example"
  
  object Foo extends Conf("foo") {
  object Bar extends Conf("bar") {
  val baz: String = confSource getProperty Prop("baz")
  val qux: String = confSource getProperty Prop("qux")
  }
  }
  }
  
  // somewhere in your application
  
  import MyAppConfig._
  
  val baz = Foo.Bar.baz // mapped to the key "com.example.foo.bar.baz" in the confSource
  val baz = Foo.Bar.qux // mapped to the key "com.example.foo.bar.qux" in the confSource
  

  Note that ConfTyped doesn't impose or depend on the way how the configuration values are loaded. It only provides a convenient way to implicitly construct the configuration key names from the nested object structure.

  The key names are obtained by calling Prop("...") method. It returns a full property key name that reflects the nesting structure of the Conf instances' names, concatenated with dot (.) and prefixed with the rootPrefix if one is provided.

  Another example of usage ConfTyped:

  val props = new java.util.Properties with ConfTyped {
  val foo = new Conf("foo") {
  val bar = new Conf("bar") {
  lazy val baz = getProperty(Prop("baz"))
  }
  }
  }
  
      props.put("foo.bar.baz", "42")
  
  println(props.foo.bar.baz) // prints 42
