BloombergLP::ball::AttributeContext_RuleEvaluationCache::knownActiveRules

Return a bit mask indicating those rules, from the set of rules provided in the last call to update, that are known to be active (as of that last call to update). If a bit in the returned value is set to 1, the rule at the corresponding index is active; however, if a bit is set to 0, the corresponding rule is either not active or has not been evaluated. Note that isDataAvailable should be called to test if this cache contains up‐to‐date evaluated rule information for the rules in which they are interested before using the result of this method.
