map

protected Vertex map(Traverser.Admin<Edge> traverser)

Specified by:

map in class ScalarMapStep<Edge,Vertex>

getParameters

public Parameters getParameters()

Description copied from interface: Parameterizing

Gets the parameters on the step.

Specified by:

getParameters in interface Parameterizing

configure

public void configure(Object... keyValues)

Description copied from interface: Configuring

Accept a configuration to the Step. 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).

Specified by:

configure in interface Configuring

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<Edge,Vertex>

Returns:

the set of requirements
