Interface Summary

Interface	Description
BidirectionalTraversalDescription	Represents a description of a bidirectional traversal.
BidirectionalUniquenessFilter
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.
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.
Evaluator	An Evaluator controls what's to be returned from a traversal and also how pruning is done.
InitialBranchState<STATE>	Factory for initial state of TraversalBranches in a traversal.
InitialStateFactory<STATE>	Deprecated use InitialBranchState instead, which has got InitialBranchState.reverse() as well.
PathEvaluator<STATE>	A PathEvaluator controls what's to be returned from a traversal and also how pruning is done.
PruneEvaluator	Deprecated because of the introduction of Evaluator which combines PruneEvaluator and filtering (Predicate of Paths).
SideSelector	Dictates which side is the current side in a bidirectional traversal to traverse the next step for.
SideSelectorPolicy	A factory for SideSelectors.
TraversalBranch	Represents a position and a RelationshipExpander 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.
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

Class Summary

Class	Description
Evaluator.AsPathEvaluator<STATE>	Exposes an Evaluator as a PathEvaluator.
Evaluators	Common Evaluators useful during common traversals.
InitialBranchState.Adapter<STATE>
InitialBranchState.State<STATE>	Branch state evaluator for an initial state.
InitialStateFactory.AsInitialBranchState<STATE>	Wraps an InitialStateFactory in a InitialBranchState
PathEvaluator.Adapter<STATE>	Adapter for PathEvaluator.
Sorting	Provides some common traversal sorting, used by TraversalDescription.sort(Comparator).

Enum Summary

Enum	Description
Evaluation	Outcome of Evaluator.evaluate(org.neo4j.graphdb.Path).
