java.lang.Objectec.rule.RuleSet
public class RuleSet
RuleSet is a set of Rules, implemented straightforwardly as an arbitrary-length array of Rules. A RuleIndividual is simply a list of RuleSets. Most typically, a RuleIndividual contains a single RuleSet, containing a variety of Rules. RuleSets contain many useful subsetting and modification functions which you can use in breeding operators which modify RuleSets and Rules.
Besides the Rules themselves, the only thing else a RuleSet contains is a pointer to a corresponding RuleSetConstraints object, which holds all of its modification parameters. See RuleSetConstraints for a description of these parameters.
In addition to serialization for checkpointing, RuleSets may read and write themselves to streams in three ways.

Prototype
Typically this should be a full "deep" clone. However, you may share certain elements with other objects rather than clone hem, depending on the situation:

public void setup(EvolutionState state, Parameter base)
Prototype
For prototypes, setup(...) is typically called once for the prototype instance; cloned instances do not receive the setup(...) call. setup(...) may be called more than once; the only guarantee is that it will get called at least once on an instance or some "parent" object from which it was ultimately cloned.
