java.lang.Objectcom.ibm.websphere.brb.implementor.RuleAND
Combination rule comprised of two or more rules which are all fired and their results ANDed together. The dependent rules may return either ConstaintReturn or java.lang.Boolean. Note that the algorithm does not short-circuit evaluation when the first false result is encountered. All dependent rules are triggered regardless of the results.
When triggering a dependent rule, if more than one rule is found with the same name, then all rules with that name will be triggered and their results will be ANDed together.
