eu.bandm.tscore.base.Util.Triplewise<T>

Enclosing class:

Util

public abstract static class Util.Triplewise<T>
extends Object

Visitor which performs the method action(Object,Object,Object) for triples of adjacent elements of an Iterable. The references wander through the positions, from the third to the first. The schema for a four element list is as follows:

      null null #0
      null #0   #1
      #0   #1   #2
      #1   #2   #3
      #2   #3   null
      #3   null null
  

DISLOC should be moved to metatools/ops/Iterators or metatools/util !?!?
