Class DummyTraverser<T>

  • All Implemented Interfaces:
    Serializable, Cloneable, Comparable<Traverser<T>>, Traverser<T>, Traverser.Admin<T>, Attachable<T>

    public final class DummyTraverser<T>
    extends EmptyTraverser<T>
    Similar to the EmptyTraverser, except the DummyTraverser can split. When it splits it generates an entirely new traverser using its supplied TraverserGenerator, leaving no trace of the initial DummyTraverser in the path. Useful for seeding nested traversals inside of start steps.
