Strategy
RuleApp
. This method is
called when the AutomatedRuleApplicationManager
comes across a rule application in which some schema variables
are not yet instantiated, or which is in some other way
incomplete. The strategy then has the opportunity to
return/provide a list of (more) complete rule applications by
feeding them into the provided
RuleAppCostCollector
