public class Body
extends ConditionSet
implements Proposition<Condition>

The body (adjacent) of a Rule. It may consist of several Conditions that are either concatenated using logical AND operators (conjunctive rule) or using logical OR operators (disjunctive rule).

This class implements the method Predicate.test(Object) to check whether the body is satisfied by an example (given as an AttributeMap) or not.
