  TraversalClassFunction<S,E> |
  TraversalExplanation | A TraversalExplanation takes a `Traversal` and, for each registered `TraversalStrategy`, it creates a mapping reflecting how each strategy alters the traversal.
  TraversalHelper |
  TraversalMatrix<S,E> | A TraversalMatrix provides random, non-linear access to the steps of a traversal by their step id.
  TraversalObjectFunction<S,E> |
  TraversalRing<A,B> |
  TraversalScriptFunction<S,E> | Deprecated As of release 3.2.0, replaced by `ScriptTraversal`.
  TraversalScriptHelper | Deprecated As of release 3.2.0, replaced by `ScriptTraversal`.
