static <STATE> PathExpander<STATE>	PathExpanders.printingWrapper(PathExpander<STATE> source, BiFunction<Path,BranchState,Boolean> pred, Paths.PathDescriptor descriptor, PrintStream out) A wrapper that uses Paths.DefaultPathDescriptor to print expanded paths that fulfill BiFunction predicate using given Paths.PathDescriptor.
static <STATE> PathExpander<STATE>	PathExpanders.printingWrapper(PathExpander<STATE> source, Paths.PathDescriptor descriptor) A wrapper that uses Paths.DefaultPathDescriptor to print expanded paths using given Paths.PathDescriptor.
PathExpander<STATE>	PathExpander.reverse() Returns a new instance with the exact expansion logic, but reversed.

Uses of PathExpander in org.neo4j.graphdb.traversal

Methods in org.neo4j.graphdb.traversal with parameters of type PathExpander

Modifier and Type	Method and Description
BranchSelector	BranchOrderingPolicy.create(TraversalBranch startBranch, PathExpander expander) Instantiates a BranchSelector with startBranch as the first branch to base a decision on "where to go next".
static Comparator<? super Path>	Sorting.endNodeRelationshipCount(PathExpander expander) Sorts Paths by the relationship count returned for its end node by the supplied expander.
TraversalDescription	TraversalDescription.expand(PathExpander<?> expander) Sets the PathExpander as the expander of relationships, discarding all previous calls to TraversalDescription.relationships(RelationshipType) and TraversalDescription.relationships(RelationshipType, Direction) or any other expand method.
<STATE> TraversalDescription	TraversalDescription.expand(PathExpander<STATE> expander, InitialBranchState<STATE> initialState) Sets the PathExpander as the expander of relationships, discarding all previous calls to TraversalDescription.relationships(RelationshipType) and TraversalDescription.relationships(RelationshipType, Direction) or any other expand method.
void	TraversalBranch.initialize(PathExpander expander, TraversalContext metadata) Initializes this TraversalBranch, the relationship iterator, Evaluation etc.
TraversalBranch	TraversalBranch.next(PathExpander expander, TraversalContext metadata) Returns the next expansion source from the expanded relationships from the current node.
