map

protected E map(Traverser.Admin<S> traverser)

Specified by:

map in class ScalarMapStep<S,E>

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.

Returns:
