Constructor Detail

TraversalMapStep

public TraversalMapStep(Traversal.Admin traversal,
                        Traversal<S,E> mapTraversal)

Method Detail

map

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

Specified by:

map in class MapStep<S,E>

getLocalChildren

public List<Traversal.Admin<S,E>> getLocalChildren()

Specified by:

getLocalChildren in interface TraversalParent

clone

public TraversalMapStep<S,E> 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 reset() is called. Moreover, the previous and next steps should be set to EmptyStep.

Specified by:

clone in interface Step<S,E>

Overrides:

clone in class AbstractStep<S,E>

Returns:

The cloned step

toString

public String toString()

Overrides:

toString in class AbstractStep<S,E>

hashCode

public int hashCode()

Overrides:

hashCode in class AbstractStep<S,E>
