| Modifier and Type | Method and Description |
|---|---|
AddPropertyStep<S> |
clone()
Cloning is used to duplicate steps for the purpose of traversal optimization and OLTP replication.
|
void |
configure(Object... keyValues)
Accept a configuration to the
Step. |

CallbackRegistry<Event.ElementPropertyChangedEvent> |
getMutatingCallbackRegistry()
Gets the callback registry for events that the step raises.
|
Parameters |
getParameters()
Gets the parameters on the step.
|
Set<TraverserRequirement> |
getRequirements()
Provide the necessary
TraverserRequirement that must be met by the traverser in order for the step to
function properly. |
Set<String> |
getScopeKeys()
Get the labels that this scoping step will access during the traversal
|

void |
setTraversal(Traversal.Admin<?,?> parentTraversal)
Set the
Traversal that this step is contained within. |

ConfiguringStep. Note that this interface extends Parameterizing and so
there is an expectation that the Step implementation will have a Parameters instance that will
house any values passed to this method. Storing these configurations in Parameters is not a requirement
however, IF the configuration is an expected option for the step and can be stored on a member field that can
be accessed on the step by more direct means (i.e. like a getter method).configure in interface Configuringprotected void sideEffect(Traverser.Admin<S> traverser)
