Package org.apache.flink.streaming.api.graph

Class StreamEdge

java.lang.Object

org.apache.flink.streaming.api.graph.StreamEdge

All Implemented Interfaces:

Serializable

@Internal
public class StreamEdge
extends Object
implements Serializable

An edge in the streaming topology. One edge like this does not necessarily gets converted to a connection between two job vertices (due to chaining/optimization).
