Constructor Details

ExecutablePlanStatsOfIteratorBasedPlan

public ExecutablePlanStatsOfIteratorBasedPlan(ExecutableOperatorStats rootOpStats,
 ExecutablePlanStats... subPlanStats)

Method Details

getRootOperatorStats

public ExecutableOperatorStats getRootOperatorStats()

Returns the stats of the root operator of the executable plan for which this object has been created.

getNumberOfSubPlans

public int getNumberOfSubPlans()

Returns the number of sub-plans of the executable plan for which this object has been created (considering sub-plans that are direct children of the root operator of the plan).

getSubPlanStats

public ExecutablePlanStats getSubPlanStats(int i)
                                    throws NoSuchElementException

Returns the stats created for the i-th sub-plan of the executable plan for which this object has been created, where i starts at index 0 (zero). If the plan had fewer sub-plans (or no sub-plans at all), then a NoSuchElementException will be thrown.

Throws:

NoSuchElementException

getSubPlanStats

public Iterable<ExecutablePlanStats> getSubPlanStats()

Returns an iterable over the stats created for the sub-plans of the executable plan for which this object has been created.
