public void setCosts(Costs nodeCosts)

从类复制的说明: 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).

覆盖:

hasDamOnPathDownTo

public PlanNode.SourceAndDamReport hasDamOnPathDownTo(PlanNode source)

从类复制的说明: 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.
