class Default
[source: scala/BufferedIterator.scala]
abstract class Default[+A]
extends PutBack[A]
Direct Known Subclasses:
Iterator.PredicatedIterator, RollbackIterator
Method Summary
protected override def defaultPeek : A
element returned when no element left to iterate over; throws NoSuchElementException by default
protected abstract def fill (sz : Int) : Seq[A]
used to fill lookahead buffer. sz can be used by implementations as a heauristic to determine how many elements are desired
override def hasNext : Boolean
Does this iterator provide another element?
override def next : A
Returns the next element.
override def peekList (sz : Int) : Seq[A]
returns the first sz elements that will be iterated by this iterator, or fewer if the iterator has less elements left to iterate over
protected[this] override def putBack (a : A) : Unit
