方法详细资料

getIterationNode

public BulkIterationNode getIterationNode()

指定者:

getIterationNode 在接口中 IterationPlanNode

getPartialSolutionPlanNode

public BulkPartialSolutionPlanNode getPartialSolutionPlanNode()

getRootOfStepFunction

public PlanNode getRootOfStepFunction()

getRootOfTerminationCriterion

public PlanNode getRootOfTerminationCriterion()

getSerializerForIterationChannel

public org.apache.flink.api.common.typeutils.TypeSerializerFactory<?> getSerializerForIterationChannel()

setSerializerForIterationChannel

public void setSerializerForIterationChannel(org.apache.flink.api.common.typeutils.TypeSerializerFactory<?> serializerForIterationChannel)

setCosts

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:

setCosts 在类中 PlanNode

参数:

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

getMemoryConsumerWeight

public int getMemoryConsumerWeight()

覆盖:

getMemoryConsumerWeight 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.

覆盖:

hasDamOnPathDownTo 在类中 SingleInputPlanNode

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.

acceptForStepFunction

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

指定者:

acceptForStepFunction 在接口中 IterationPlanNode
