getParameters
public Parameters getParameters()
Description copied from interface:Parameterizing
Gets the parameters on the step.- Specified by:
getParameters
in interfaceParameterizing
-
configure
public void configure(Object... keyValues)
Description copied from interface:Configuring
Accept a configuration to theStep
. Note that this interface extendsParameterizing
and so there is an expectation that theStep
implementation will have aParameters
instance that will house any values passed to this method. Storing these configurations inParameters
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).- Specified by:
configure
in interfaceConfiguring
-
filter
protected boolean filter(Traverser.Admin<S> traverser)
- Specified by:
filter
in classFilterStep<S extends Element>
-
toString
public String toString()
-
getHasContainers
public List<HasContainer> getHasContainers()
- Specified by:
getHasContainers
in interfaceHasContainerHolder
-
removeHasContainer
public void removeHasContainer(HasContainer hasContainer)
- Specified by:
removeHasContainer
in interfaceHasContainerHolder
-
addHasContainer
public void addHasContainer(HasContainer hasContainer)
- Specified by:
addHasContainer
in interfaceHasContainerHolder
-
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.
-
clone
public HasStep<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
.
