<:< operator in scala

Question

Can anybody provide some details on <:< operator in scala. I think:

if(apple <:< fruit)  //checks if apple is a subclass of fruit.         


        

Answer 1

Hmm... I can't seem to find "<:<" anywhere as well, but "<:" denotes subtyping. From http://jim-mcbeath.blogspot.com/2008/09/scala-syntax-primer.html#types :

List[T] forSome { type T <: Component }

In the above example, we are saying T is some type which is a subtype of Component.
