## Class MathStep.TinkerExpression

- java.lang.Object
- - org.apache.tinkerpop.gremlin.process.traversal.step.map.MathStep.TinkerExpression

- All Implemented Interfaces:
    Serializable
  Enclosing class:
    MathStep<S>

      public static class MathStep.TinkerExpression
      extends Object
      implements Serializable

  A wrapper for the `Expression` class. That class is not marked `Serializable` and therefore gives problems in OLAP specifically with Spark. This wrapper allows the `Expression` to be serialized in that context with Java serialization.
