Splitter

trait Splitter[+T] extends Iterator[T]

A splitter (or a split iterator) can be split into more splitters that traverse over disjoint subsets of elements.

Abstract methods

def split: Seq[Splitter[T]]

Splits the iterator into a sequence of disjunct views.

Splits the iterator into a sequence of disjunct views.

Returns a sequence of split iterators, each iterating over some subset of the elements in the collection. These subsets are disjoint and should be approximately equal in size. These subsets are not empty, unless the iterator is empty in which case this method returns a sequence with a single empty iterator. If the splitter has more than two elements, this method will return two or more splitters.

Implementors are advised to keep this partition relatively small - two splitters are already enough when partitioning the collection, although there may be a few more.

'''Note:''' this method actually invalidates the current splitter.

Returns

a sequence of disjunct iterators of the collection
