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
-
clone
public ComputerResultStep<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
.- Specified by:
clone
in interfaceStep<ComputerResult,S>
- Overrides:
clone
in classAbstractStep<ComputerResult,S>
- Returns:
- The cloned step
