- org.apache.tinkerpop.gremlin.process.traversal.step.util.AbstractStep<S,E>
- - org.apache.tinkerpop.gremlin.process.traversal.step.map.MapStep<S,E>
  - - org.apache.tinkerpop.gremlin.process.traversal.step.map.ScalarMapStep<S,String>
    - - org.apache.tinkerpop.gremlin.process.traversal.step.map.AsStringStep<S>

All Implemented Interfaces:

Serializable, Cloneable, Iterator<Traverser.Admin<String>>, Step<S,String>
```
public final class AsStringStep<S>
extends ScalarMapStep<S,String>
```
Reference implementation for asString() step, a mid-traversal step which returns the incoming traverser value as a string. Null values are returned as a string value "null".
