bradkarels / scalaTraitInstanitationViaAnonClass.scala

Created May 11, 2016 13:15

When you see a trait being "instantiated", be mindful that what is actually happening is that an anonymous class is being instantiated for you.

	// Given a simple trait
	trait NiceTrait {
	def isNice(s: String): Boolean = s match {
	case "nice" => true
	case _ => false
	}
	}

	//It is possible to "instantiate" this trait two ways, manually create a class and instantiate that:
	class MyClass extends NiceTrait
