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.
