IterableFactory

trait IterableFactory[+CC[_]] is a base trait for companion objects for specific collections which provides a number of operations to create a specific collection with the type specified by the CC type constructor; this is sometimes called target-type driven building because the type of the source collection is ignored. Most of the companion objects in the collection library extend this trait, which makes it possible to use them in places where IterableFactory is expected. 

As this is the main abstraction that allows to build a collection from scratch, it is useful to know which methods it supplies. All of them return CC[A]. The following table contains a short summary:

Arguably, IterableFactory provides a lot of different possibilities to create a collection of a desired type.
