- Interface Summary
  Interface | Description
  --- | ---
  Path | A Path denotes a particular walk through a `Graph` as defined by a `Traversal`.
  Step<S,E> | A `Step` denotes a unit of computation within a `Traversal`.
  Translator<S,T> | A Translator will translate `Bytecode` into another representation.
  Translator.ScriptTranslator | Translates bytecode to a Script representation.
  Translator.ScriptTranslator.TypeTranslator | Provides a way for the `Translator.ScriptTranslator` to convert various data types to their string representations in their target language.
  Translator.StepTranslator<S extends TraversalSource,T extends Traversal.Admin<?,?>> | Translates bytecode to actual steps.
  Traversal<S,E> | A `Traversal` represents a directed walk over a `Graph`.
  Traversal.Admin<S,E> |
  TraversalEngine | A TraversalEngine is a test component that helps determine the engine on which a traversal test will execute.
  TraversalSideEffects | A `Traversal` can maintain global sideEffects.
  TraversalSource | A `TraversalSource` is used to create `Traversal` instances.
  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`.

- Class Summary
  Class | Description
  --- | ---
  AnonymousTraversalSource<T extends TraversalSource> | Provides a unified way to construct a `TraversalSource` from the perspective of the traversal.
  Bindings | Bindings are used to associate a variable with a value.
  Bytecode | When a `TraversalSource` is manipulated and then a `Traversal` is spawned and mutated, a language agnostic representation of those mutations is recorded in a bytecode instance.
  Bytecode.Binding<V> |
  Bytecode.Instruction |
  CoreTraversalTest |
  IO | Fields that can be provided to the `GraphTraversalSource.io(String)` using the `GraphTraversal.with(String,Object)` step modulator to provide additional configurations.
  P<V> | Predefined `Predicate` values that can be used with
  Path.Exceptions |
  SackFunctions |
  Script | General representation of script
  TextP | Predefined `Predicate` values that can be used as `String` filters.
  Translator.ScriptTranslator.AbstractTypeTranslator |
  Traversal.Exceptions | A collection of `Exception` types associated with Traversal execution.
  Traversal.Symbols |
  TraversalInterruptionComputerTest |
  TraversalInterruptionTest |
  TraversalSideEffects.Exceptions |
  TraversalSource.Symbols |
  TraversalStrategies.GlobalCache |

- Enum Summary
  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.
  GraphOp | A `GraphOp` or "graph operation" is a static `Bytecode` form that does not translate to a traversal but instead refers to a specific function to perform on a graph instance.
  Operator | A set of `BinaryOperator` instances that handle common operations for traversal steps.
  Order | Provides `Comparator` instances for ordering traversers.
  Pop | A `Path` may have multiple values associated with a single label.
  SackFunctions.Barrier |
  Scope | Many `Step` instance can have a variable scope which alter the manner in which the step will behave in relation to how the traversers are processed.
  Text | `Text` is a `BiPredicate` that determines whether the first string starts with, starts not with, ends with, ends not with, contains or does not contain the second string argument.
