Concrete methods

def toScalaAs[B]: IterableOnce[B]

Wraps a java iterator into a scala iterator, and casts it's elements. This is faster than jIterator.asScala.map(_.asInstanceOf[B]) because

Wraps a java iterator into a scala iterator, and casts it's elements. This is faster than jIterator.asScala.map(_.asInstanceOf[B]) because

  1. .asScala conversion is actually quite slow: multiple method calls and a match without @switch
  2. no additional map step that iterates and creates yet another iterator
