ConjoinStep

public ConjoinStep(Traversal.Admin traversal,
                   String delimiter)

Method Detail

getStepName

public String getStepName()

Description copied from interface: ListFunction

Template method used for retrieving the implementing Step's name.

Specified by:

getStepName in interface ListFunction

Returns:

this step's name.

map

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

Specified by:

map in class ScalarMapStep<S,String>

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,String>

Returns:

the set of requirements

clone

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

Specified by:

clone in interface Step<S,String>

Overrides:

clone in class AbstractStep<S,String>

Returns:

The cloned step

hashCode

public int hashCode()

Overrides:

hashCode in class AbstractStep<S,String>
