| Step<S,E> | |
| Traversal<S,E> | |
| Traversal.Admin<S,E> | |
| TraversalEngine | 
 A TraversalEngine is reponsible for executing a  
Traversal. | 
| TraversalEngine.Builder | |
| TraversalSideEffects | 
 A  
Traversal can maintain global sideEffects. | 
| TraversalSource | 
 A  
TraversalSource is responsible for generating a Traversal. | 
| TraversalSource.Builder<C extends TraversalSource> | |
| TraversalStrategies | 
 A  
Traversal maintains a set of TraversalStrategy instances within a TraversalStrategies object. | 
| TraversalStrategy<S extends TraversalStrategy> | 
 A  
TraversalStrategy defines a particular atomic operation for mutating a Traversal prior to its evaluation. | 
| TraversalStrategy.DecorationStrategy | 
 Implemented by strategies that adds "application logic" to the traversal (e.g. 
 | 
| TraversalStrategy.FinalizationStrategy | 
 Implemented by strategies that do final behaviors that require a fully compiled traversal to work (e.g. 
 | 
| TraversalStrategy.OptimizationStrategy | 
 Implemented by strategies that rewrite the traversal to be more efficient, but with the same semantics
 (e.g. 
 | 
| TraversalStrategy.ProviderOptimizationStrategy | 
 Implemented by strategies that rewrite the traversal to be more efficient, but with the same semantics. 
 | 
| TraversalStrategy.VerificationStrategy | 
 Implemented by strategies where there is no more behavioral tweaking of the traversal required. 
 | 
| Traverser<T> | 
 A  
Traverser represents the current state of an object flowing through a Traversal. | 
| Traverser.Admin<T> | 
 The methods in System.Traverser are useful to underlying Step and Traversal implementations. 
 | 
| TraverserGenerator | 
 A TraverserGenerator will generate traversers for a particular  
Traversal. |

| NumberHelper | |

| Path.Exceptions | |
| SackFunctions | |
| Traversal.Exceptions | 
 A collection of  
Exception types associated with Traversal execution. | 
| TraversalSideEffects.Exceptions | |
| TraversalStrategies.GlobalCache | 
| Enum | Description | 
|---|---|
| Compare | 
Compare is a BiPredicate that determines whether the first argument is ==, !=,
 >, >=, <, <= to the second argument. | 
| Contains | 
Contains is a BiPredicate that evaluates whether the first object is contained within (or not
 within) the second collection object. | 
| Operator | |
| Order | |
| Pop | |
| SackFunctions.Barrier | |
| Scope | 
 Many  
Step instance can have a variable scope. |
