Class ManagementEdge

java.lang.Object

org.apache.flink.runtime.managementgraph.ManagementAttachment

org.apache.flink.runtime.managementgraph.ManagementEdge

public final class ManagementEdge
extends ManagementAttachment

This class implements a directed edge of a ManagementGraph. The edge is derived from a channel of the actual execution graph.

This class is not thread-safe.
