accept

public void accept(org.apache.flink.util.Visitor<PlanNode> visitor)

getPredecessors

public Iterable<PlanNode> getPredecessors()

从接口复制的说明: DumpableNode

Gets an iterator over the predecessors.

指定者:

getPredecessors 在接口中 DumpableNode<PlanNode>

指定者:

getPredecessors 在类中 PlanNode

返回:

An iterator over the predecessors.

getInputs

public Iterable<Channel> getInputs()

指定者:

getInputs 在类中 PlanNode

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.

指定者:

hasDamOnPathDownTo 在类中 PlanNode

参数:

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

返回:

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