Interface TraversalStrategy

All Known Implementing Classes:

AbstractTraversalStrategy, ComparatorHolderRemovalStrategy, DedupOptimizerStrategy, EngineDependentStrategy, IdentityRemovalStrategy, LabeledEndStepStrategy, MatchWhereStrategy, ReducingStrategy, RouteStrategy, SideEffectCapStrategy, SideEffectRegistrationStrategy

public interface TraversalStrategy

A TraversalStrategy defines a particular atomic operation for mutating a Traversal prior to its evaluation. Traversal strategies are typically used for optimizing a traversal for the particular underlying graph engine. Traversal strategies implement Comparable and thus are sorted to determine their evaluation order. A TraversalStrategy should not have a public constructor as they should not maintain state between applications. Make use of a singleton instance() object to reduce object creation on the JVM.
