RelationshipExpander | Deprecated. in favor or `PathExpander`.
RelationshipType | A relationship type is mandatory on all relationships and is used to navigate the node space.
ReturnableEvaluator | Deprecated. because of the introduction of a new traversal framework, see more information at `TraversalDescription` and `Traversal` and the new traversal framework's equivalent `Predicate`.
StopEvaluator | Deprecated. because of the introduction of a new traversal framework, see more information at `TraversalDescription` and `Traversal` and the new traversal framework's equivalent `Evaluator`.
Transaction | A programmatically handled transaction.
TraversalPosition | Encapsulates information about the current traversal position.
Traverser | Deprecated. because of an unnatural and too tight coupling with `Node`.

Class Summary
DynamicRelationshipType | A dynamically instantiated and named `RelationshipType`.

Enum Summary
Direction | Defines relationship directions used when getting relationships from a node or when creating traversers.
Traverser.Order | Defines a traversal order as used by the traversal framework.
