Uses of Pair in se.liu.ida.hefquin.engine.queryproc

Methods in se.liu.ida.hefquin.engine.queryproc that return Pair

Modifier and Type	Method	Description
Pair<PhysicalPlan,QueryPlanningStats>	QueryPlanner.createPlan(Query query, QueryProcContext ctxt)
Pair<LogicalPlan,SourcePlanningStats>	SourcePlanner.createSourceAssignment(Query query, QueryProcContext ctxt)	The logical plan returned by this method is a source assignment (see Definition 8 of our FedQPL paper); that is, the only types of operators that it contains are request operators ( invalid reference LogicalOpRequest ), multiway joins ( invalid reference LogicalOpMultiwayJoin ), and multiway unions ( invalid reference LogicalOpMultiwayUnion ).
Pair<PhysicalPlan,PhysicalOptimizationStats>	PhysicalOptimizer.optimize(LogicalPlan initialPlan, QueryProcContext ctxt)

Uses of Pair in se.liu.ida.hefquin.engine.queryproc.impl.loptimizer.heuristics

Methods in se.liu.ida.hefquin.engine.queryproc.impl.loptimizer.heuristics that return Pair

Modifier and Type	Method	Description
protected Pair<LogicalPlan,Integer>	CardinalityBasedJoinOrderingBase.determineNextPlan(List<LogicalPlan> selectedPlans, int joinCardOfSelectedPlans, List<LogicalPlan> 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.
