Why isn't this Scala method documented in Scaladocs?

Question

I've been told that Scaladocs is the best source for Scala API documentation: http://www.scala-lang.org/api/current/index.html

I've found an example using scala.io.Source.fromURL(url).getLines

The example works, but fromURL is not in that site. Where can I find a more exhaustive documentation on the methods available?

Answer 1

Are you sure that fromURL isn't part of the object and not the trait or class? I found it in the object's API documents: here.

Answer 2

If you see a green banner with a big "C", then you are looking at the class definition. Click the "companion" link to get to the companion object. This page will present a blue banner with a big "O". Your method is there.

In the side panel, the little 'c' and 'o' icons are separate links. You should choose the 'o' (object) when you are calling a static method (or method on the companion object, in Scala parlance).
