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

All Implemented Interfaces:

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