setCosts

public void setCosts(Costs nodeCosts)

Description copied from class: PlanNode

Sets the basic cost for this node to the given value, and sets the cumulative costs to those costs plus the cost shares of all inputs (regular and broadcast).

Overrides:

setCosts in class PlanNode

Parameters:

nodeCosts - The already knows costs for this node (this cost a produces by a concrete OptimizerNode subclass.

getMemoryConsumerWeight

public int getMemoryConsumerWeight()

Overrides:

getMemoryConsumerWeight in class PlanNode

hasDamOnPathDownTo

public PlanNode.SourceAndDamReport hasDamOnPathDownTo(PlanNode source)

Description copied from class: PlanNode

Checks whether this node has a dam on the way down to the given source node. This method returns either that (a) the source node is not found as a (transitive) child of this node, (b) the node is found, but no dam is on the path, or (c) the node is found and a dam is on the path.

Overrides:

hasDamOnPathDownTo in class DualInputPlanNode

Parameters:

source - The node on the path to which the dam is sought.

Returns:

The result whether the node is found and whether a dam is on the path.

acceptForStepFunction

public void acceptForStepFunction(Visitor<PlanNode> visitor)

Specified by:

acceptForStepFunction in interface IterationPlanNode

mergeBranchPlanMaps

protected void mergeBranchPlanMaps(Map<OptimizerNode,PlanNode> branchPlan1,
                                   Map<OptimizerNode,PlanNode> branchPlan2)

Merging can only take place after the solutionSetDelta and nextWorkset PlanNode has been set, because they can contain also some of the branching nodes.

Overrides:

mergeBranchPlanMaps in class PlanNode

mergeBranchPlanMaps

protected void mergeBranchPlanMaps()
