org.apache.tinkerpop.gremlin.process.traversal.step.map

Class MapStep<S,E>

java.lang.Object

org.apache.tinkerpop.gremlin.process.traversal.step.util.AbstractStep<S,E>

org.apache.tinkerpop.gremlin.process.traversal.step.map.MapStep<S,E>

All Implemented Interfaces:

Serializable, Cloneable, Iterator<Traverser.Admin<E>>, Step<S,E>

Direct Known Subclasses:

ScalarMapStep, SelectOneStep, SelectStep, TraversalMapStep, TraversalSelectStep

public abstract class MapStep<S,E>
extends AbstractStep<S,E>

A marker base class that designates an extending Step as a "Map" step which will transform the object of one Traverser into another. In many cases, it may be easier to simply extend from ScalarMapStep which has a straightforward implementation pattern.
