All Known Implementing Classes:

ListShufflerCImpl

public interface ListShufflerC

extends CreateC, CreateS, DropC, DropS

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.

java.lang.Object	setUniformRandom(java.lang.Object dist) the setUniformRandom: method connects the supplied uniform distribution to the Shuffler (run after createBegin:).
