org.apache.flink.optimizer.dag.OptimizerNode.UnclosedBranchDescriptor

封闭类:

OptimizerNode

public static final class OptimizerNode.UnclosedBranchDescriptor
extends Object

Description of an unclosed branch. An unclosed branch is when the data flow branched (one operator's result is consumed by multiple targets), but these different branches (targets) have not been joined together.

UnclosedBranchDescriptor

protected UnclosedBranchDescriptor(OptimizerNode branchingNode,
                                   long joinedPathsVector)

Creates a new branching descriptor.

参数:

branchingNode - The node where the branch occurred (the node with multiple outputs).

joinedPathsVector - A bit vector describing which branches are tracked by this descriptor. The bit vector is one, where the branch is tracked, zero otherwise.
