clone()
Cloning is used to duplicate steps for the purpose of traversal optimization and OLTP replication.

Accept a configuration to the
Step. |

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. |

public Parameters getParameters()
ParameterizinggetParameters in interface Parameterizingpublic void configure(Object... keyValues)
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 boolean filter(Traverser.Admin<S> traverser)

StepStep.reset() is called. Moreover, the previous and next steps should be set to EmptyStep.Copyright © 2013–2021 Apache Software Foundation. All rights reserved.
