override def elements : Iterator[A]
Returns an iterator over all elements of this list.
def get (n : Int) : Option[A]
Returns the nth element of this list or None if this element does not exist.
override def last : A
Returns the last element of this list.
def length : Int
Returns the length of this list.
protected def prependElem (elem : A) : Unit
protected def reset : Unit
protected override def stringPrefix : java.lang.String
Defines the prefix of this object's toString representation.
override def toList : List[A]
Returns an instance of scala.List containing the same sequence of elements.
