class GroupedIterator [B >: A] 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.

def addString(b: StringBuilder, start: String, sep: String, end: String): StringBuilder
Appends all elements of this iterator to a string builder using start, end, and separator strings.
Appends all elements of this iterator to a string builder using start, end, and separator strings. The written text begins with the string start and ends with the string end. Inside, the string representations (w.r.t. the method toString) of all elements of this iterator are separated by the string sep.
Example:
```
scala> val a = List(1,2,3,4)
a: List[Int] = List(1, 2, 3, 4)

scala> val b = new StringBuilder()
b: StringBuilder =

scala> a.addString(b , "List(" , ", " , ")")
res5: StringBuilder = List(1, 2, 3, 4)
```
b
the string builder to which elements are appended.
start
the starting string.
sep
the separator string.
end
the ending string.
returns
the string builder b to which elements were appended.

def sliding[B >: A](size: Int, step: Int = 1): GroupedIterator[B]
Returns an iterator which presents a "sliding window" view of this iterator.
Returns an iterator which presents a "sliding window" view of this iterator. The first argument is the window size, and the second argument step is how far to advance the window on each iteration. The step defaults to 1.
The default GroupedIterator can be configured to either pad a partial result to size size or suppress the partial result entirely.
Example usages:
```

(1 to 5).iterator.sliding(3).toList
// Returns List(List(1, 2, 3, 4), List(4, 5))

// Illustrating that withPadding's argument is by-name.

To access this member you can use a type ascription:
(abstractIterator: IterableOnceExtensionMethods[A]).mkString(start, sep, end)
Definition Classes
IterableOnceExtensionMethods
Annotations
@deprecated
Deprecated
(Since version 2.13.0) Use .iterator().mkString instead of .mkString on IterableOnce
def toArray[B >: A](implicit arg0: ClassTag[B]): Array[B]

Implicit
This member is added by an implicit conversion from AbstractIterator[A] to IterableOnceExtensionMethods[A] performed by method iterableOnceExtensionMethods in strawman.collection.IterableOnce.
Definition Classes
IterableOnceExtensionMethods
Annotations
@deprecated
Deprecated
(Since version 2.13.0) Use ArrayBuffer.fromIterable(it).toArray instead of it.toArray on Iterable (wrap Iterators with View.fromIterator first)
def toBuffer[B >: A]: Buffer[B]

Implicit
This member is added by an implicit conversion from AbstractIterator[A] to IterableOnceExtensionMethods[A] performed by method iterableOnceExtensionMethods in strawman.collection.IterableOnce.
