Class FieldValue

java.lang.Object

org.jpmml.evaluator.FieldValue

All Implemented Interfaces:

Serializable, Comparable<FieldValue>

Direct Known Subclasses:

CategoricalValue, ContinuousValue, OrdinalValue

public abstract class FieldValue
extends Object
implements Comparable<FieldValue>, Serializable

A field value representation that meets the requirements of PMML type system.

Type information has two components to it:

• Operational type. Determines supported type equality and type comparison operations.
• Data type. Determines supported type conversions.

A field value is created after a field. It may be later refined by transformations and functions.
