org.dmfs.jems2.iterator.Clustered<T>

All Implemented Interfaces:

Iterator<Iterable<T>>

public final class Clustered<T>
extends BaseIterator<Iterable<T>>

An Iterator decorator which clusters consecutive elements of another Iterator by the result of a Comparator. Consecutive elements which compare to 0 go into the same cluster. The original order of the elements remains the same.

 Clustered(Comparator.naturalOrder(), [5, 5, 5, 3, 3, 4, 4, 4, 5, 5, 2, 2]) ->
 [
   [5, 5, 5],
   [3, 3],
   [4, 4, 4],
   [5, 5],
   [2, 2]
 ]
