34.1. Main concepts

Here follows a short explanation of all different methods that can modify or add to a traversal description.

  • Pathexpanders — define what to traverse, typically in terms of relationship direction and type.
  • Order — for example depth-first or breadth-first.
  • Uniqueness — visit nodes (relationships, paths) only once.
  • Evaluator — decide what to return and whether to stop or continue traversal beyond the current position.
  • Starting nodes where the traversal will begin.

See Section 34.2, “Traversal Framework Java API” for more details.
