protected Pair<CardinalityBasedJoinOrderingBase.AnnotatedLogicalPlan,Integer>	CardinalityBasedJoinOrderingBase.determineNextPlan(List<CardinalityBasedJoinOrderingBase.AnnotatedLogicalPlan> selectedPlans, int joinCardOfSelectedPlans, List<CardinalityBasedJoinOrderingBase.AnnotatedLogicalPlan> nextCandidates)	Returns the plan from the given list of next candidates that has the lowest join cardinality with a plan consisting of the given selected plans, and that join cardinality will be returned as well.
protected abstract int[]	CardinalityBasedJoinOrderingBase.estimateCardinalities(LogicalPlan[] plans)	Implementations of this function determine or estimate the cardinality of each of the given plans.
protected int[]	CardinalityBasedJoinOrderingWithRequests.estimateCardinalities(LogicalPlan[] plans)
protected abstract int	CardinalityBasedJoinOrderingBase.estimateJoinCardinality(List<CardinalityBasedJoinOrderingBase.AnnotatedLogicalPlan> selectedPlans, int joinCardOfSelectedPlans, CardinalityBasedJoinOrderingBase.AnnotatedLogicalPlan nextCandidate)	Implementations of this function estimate the cardinality of the join between the result of joining the given selected plans and the result of the given next candidate.
protected void	CardinalityBasedJoinOrderingBase.reorder(LogicalPlan[] plans)	Changes the order of the subplans in the given array by using the greedy algorithm described above for this class.
