class GroupedIterator
[source: scala/collection/Iterator.scala]
class GroupedIterator[B >: A](self : Iterator[A], size : Int, step : Int)
extends Iterator[Seq[B]]
A flexible iterator for transforming an Iterator[A] into an Iterator[Seq[A]], with configurable sequence size, step, and strategy for dealing with elements which don't fit evenly. Typical uses can be achieved via methods `grouped' and `sliding'.
Method Summary
def hasNext : Boolean
Does this iterator provide another element?
def next : List[B]
Returns the next element of this iterator.
def withPadding (x : => B) : GroupedIterator[B]
Public functions which can be used to configure the iterator before use.
def withPartial (x : Boolean) : GroupedIterator[B]
