scalax.collection.ForeachBasedDetachingIterable
trait ForeachBasedDetachingIterable[+A] extends Iterable[A]

Substitute for Scala 2.12 Traversable to continue support for collections that cannot implement hasNext/next easily. The methods of Scala 2.13's IterableOnce are implemented in terms of foreach.

All methods with a collection result detach from this Iterable to Vector. This makes sense whenever the foreach implementation

  • causes significant computation overhead or
  • is not valid for arbitrary subcollections.
