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.
