Constructor Detail

StoreStep

public StoreStep(Traversal.Admin traversal,
                 String sideEffectKey)

Method Detail

sideEffect

protected void sideEffect(Traverser.Admin<S> traverser)

Specified by:

sideEffect in class SideEffectStep<S>

getSideEffectKey

public String getSideEffectKey()

Description copied from interface: SideEffectCapable

The side-effect key of the step.

Specified by:

getSideEffectKey in interface SideEffectCapable<Collection,Collection>

Returns:

the side-effect key

toString

public String toString()

Overrides:

toString in class AbstractStep<S,S>

getLocalChildren

public List<Traversal.Admin<S,Object>> getLocalChildren()

Specified by:

getLocalChildren in interface TraversalParent

modulateBy

public void modulateBy(Traversal.Admin<?,?> storeTraversal)

Specified by:

modulateBy in interface ByModulating

getRequirements

public Set<TraverserRequirement> getRequirements()

Description copied from interface: Step

Provide the necessary TraverserRequirement that must be met by the traverser in order for the step to function properly. The provided default implements returns an empty set.

Specified by:

getRequirements in interface Step<S,S>

Returns:

the set of requirements

clone

public StoreStep<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 when reset() is called. Moreover, the previous and next steps should be set to EmptyStep.

Specified by:

clone in interface Step<S,S>

Overrides:

clone in class AbstractStep<S,S>

Returns:

The cloned step

setTraversal

public void setTraversal(Traversal.Admin<?,?> parentTraversal)

Description copied from interface: Step

Set the Traversal that this step is contained within.

Specified by:

setTraversal in interface Step<S,S>

Overrides:

setTraversal in class AbstractStep<S,S>

Parameters:

parentTraversal - the new traversal for this step

hashCode

public int hashCode()

Overrides:

hashCode in class AbstractStep<S,S>
