All Implemented Interfaces:

java.io.Serializable

public class CompositeFlowExecutionKey
extends FlowExecutionKey

A flow execution key that consists of two parts:

1. A executionId, identifying a logical FlowExecution that is running.
2. A snapshotId, identifying a physical flow execution snapshot that can be restored.
