Method Details

getLowRange

public Long getLowRange()

Description copied from interface: RangeLocalStepContract

Retrieves the lower bound of the range.

Specified by:

getLowRange in interface RangeLocalStepContract<S>

Specified by:

getLowRange in interface Ranging

Returns:

the value representing the lower bound of the range

getHighRange

public Long getHighRange()

Description copied from interface: RangeLocalStepContract

Retrieves the higher bound of the range.

Specified by:

getHighRange in interface RangeLocalStepContract<S>

Specified by:

getHighRange in interface Ranging

Returns:

the higher bound of the range as an object of type V

map

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

map in class ScalarMapStep<S,S>

toString

public String toString()

Overrides:

toString in class AbstractStep<S,S>

hashCode

public int hashCode()

Overrides:

hashCode in class AbstractStep<S,S>

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
