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>
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
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
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.
