planHash

public int planHash(@Nonnull
                    PlanHashable.PlanHashKind hashKind)

Description copied from interface: PlanHashable

Return a hash similar to hashCode, but with the additional guarantee that is is stable across JVMs.

Parameters:

hashKind - the "kind" of hash to calculate. Each kind of hash has a particular logic with regards to included and excluded items.

Returns:

a stable hash code

logPlanStructure

public void logPlanStructure(StoreTimer timer)

Description copied from interface: QueryPlan

Adds one to an appropriate StoreTimer counter for each plan and subplan of this plan, allowing tracking of which plans are being chosen (e.g. index scan vs. full scan).

Parameters:

timer - the counters to increment

rewritePlannerGraph

@Nonnull
public PlannerGraph rewritePlannerGraph(@Nonnull
                                        List<? extends PlannerGraph> childGraphs)

Rewrite the planner graph for better visualization of a query index plan.

Parameters:

childGraphs - planner graphs of children expression that already have been computed

Returns:

the rewritten planner graph that models this operator as a logical nested loop join joining an outer table of values in the IN clause to the correlated inner result of executing (usually) a index lookup for each bound outer value.
