ListShuffler -- A class to randomize the order of a given Swarm List
ListShuffler randomizes the order of the elements in a List; either the whole list or the num lowest elements. The list must be supplied. An uniform distribution can be supplied, or the system- supplied uniformUnsRand is used. The algorithm is from Knuth. All these methods modify the underlying collection, so any indexes should always be regenerated.
(id <Zone>)aZone setUniformRandom: dist
The create:setUniformRandom method creates the Shuffler and connects the supplied distribution object.
- setUniformRandom: dist
the setUniformRandom: method connects the supplied uniform distribution to the Shuffler (run after createBegin:).
- shufflePartialList: list Num:
the shufflePartialList:Num method randomizes the order of the 'num' lowest elements of the list, or the whole list if (num > size of list).
- shuffleWholeList: list
the shuffleWholeList method randomizes the whole list.
