clone
public IsStep<S> clone()
Description copied from interface:Step
Cloning is used to duplicate steps for the purpose of traversal optimization and OLTP replication. When cloning a step, it is important that the steps, the cloned step is equivalent to the state of the step whenStep.reset()
is called. Moreover, the previous and next steps should be set toEmptyStep

getRequirements
public Set<TraverserRequirement> getRequirements()
Description copied from interface:Step
Provide the necessaryTraverserRequirement
that must be met by the traverser in order for the step to function properly. The provided default implements returns an empty set.- Returns:
- the set of requirements
