Class	Description
BidirectionalTraversalDescription	Represents a description of a bidirectional traversal.
BranchCollisionDetector	In a bidirectional traversal there's one traversal from each start/end side and they will probably meet somewhere in the middle and the full paths are formed.
BranchCollisionPolicies	A catalogue of convenient branch collision policies, see BranchCollisionPolicy
BranchCollisionPolicy	A `BranchCollisionPolicy` defines when a collision is detected and accepted in a bidirectional traversal, see BidirectionalTraversalDescription.
BranchOrderingPolicies	A catalog of convenient branch ordering policies.
BranchOrderingPolicy	Creator of BranchSelector instances with a starting point to base the first decision on.
BranchSelector	Decides "where to go next" in a traversal.
BranchState<STATE>	Accessor for a state associated with a TraversalBranch during a traversal.
Evaluation	Outcome of Evaluator.evaluate(org.neo4j.graphdb.Path).
Evaluator	An Evaluator controls what's to be returned from a traversal and also how pruning is done.
Evaluator.AsPathEvaluator<STATE>	Exposes an Evaluator as a PathEvaluator.
Evaluators	Common Evaluators useful during common traversals.
InitialBranchState<STATE>	Factory for initial state of TraversalBranches in a traversal.
InitialBranchState.State<STATE>	Branch state evaluator for an initial state.
PathEvaluator<STATE>	A PathEvaluator controls what's to be returned from a traversal and also how pruning is done.
PathEvaluator.Adapter<STATE>	Adapter for PathEvaluator.
Paths	Utilities for Path objects.
Paths.DefaultPathDescriptor<T extends Path>	The default Paths.PathDescriptor used in common toString() representations in classes implementing Path.
Paths.PathDescriptor<T extends Path>	Provides hooks to help build a string representation of a Path.
Paths.SingleNodePath
SideSelector	Dictates which side is the current side in a bidirectional traversal to traverse the next step for.
SideSelectorPolicies	A catalogue of convenient side selector policies for use in bidirectional traversals.
SideSelectorPolicy	A factory for SideSelectors.
TraversalBranch	Represents a position and a PathExpander with a traversal context, for example parent and an iterator of relationships to go next.
TraversalContext	Provides a context for TraversalBranches which they need to move further and report their progress.
TraversalDescription	Represents a description of a traversal.
TraversalMetadata	Provides metadata about a traversal.
Traverser	This interface represents the traverser which is used to step through the results of a traversal.
Uniqueness	A catalog of convenient uniqueness factories.
UniquenessFactory	Factory for UniquenessFilter filters, it can supply the created UniquenessFilter with an optional parameter which is up to the filter itself to validate and make sense of.
UniquenessFilter	Interface for filters preventing the traversal from visiting already seen parts of the graph.
