Remarks
Applications implement evaluators for fields by deriving from this class. The evaluator object instantiated from this class is obtained from the field evaluator loader using the evaluator ID stored in the field. An evaluator class can be implemented for each type of field, or a single evaluator class can support multiple types of fields.
