class FieldRef extends FieldExpression with MixedEvaluator
Field references are simply pass-throughs to fields previously defined in the DataDictionary, a DerivedField, or a result field. For example, they are used in clustering models in order to define center coordinates for fields that don't need further normalization.
A missing input will produce a missing result. The optional attribute mapMissingTo may be used to map a missing result to the value specified by the attribute. If the attribute is not present, the result remains missing.
