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<DefaultTraversalMetrics,DefaultTraversalMetrics>

Returns:

the side-effect key

next

public Traverser.Admin<S> next()

Specified by:

next in interface Iterator<Traverser.Admin<S>>

Overrides:

next in class AbstractStep<S,S>

hasNext

public boolean hasNext()

Specified by:

hasNext in interface Iterator<Traverser.Admin<S>>

Overrides:

hasNext in class AbstractStep<S,S>

generateFinalResult

public DefaultTraversalMetrics generateFinalResult(DefaultTraversalMetrics tm)

Description copied from interface: Generating

Post-process the side-effect and return the post-processed side-effect. The default implementation is simply the identity function and returns the argument.

Specified by:

generateFinalResult in interface Generating<DefaultTraversalMetrics,DefaultTraversalMetrics>

Parameters:

tm - the pre-processed side-effect.

Returns:

the post-processed side-effect.

onGraphComputer

public void onGraphComputer()

Description copied from interface: GraphComputing

The step will be executing on a GraphComputer.

Specified by:

onGraphComputer in interface GraphComputing
