org.hibernate.engine.internal.JoinSequence
A sequence of {@link Join} delegates to make it "easier" to work with joins. The "easier" part is obviouslysubjective ;)
Additionally JoinSequence is a directed graph of other JoinSequence instances, as represented by the {@link #next} ({@link #setNext(JoinSequence)}) pointer. @author Gavin King @author Steve Ebersole @see JoinFragment
