. For each row of input, subclasses should first set the predicted values in
the predictedFields
array and then invoke AbstractPredictor.pushPrediction()
.
Subclasses should not invoke pushEndOfData
since that is automatically handled by
the base class.execute

model
- The input PMML modelinput
- The input datapredictedFields
- An array of fields that reference the predicted field locations. The
array positionally corresponds to the type returned by AbstractPredictor.predictedType(PMMLModelSpec)
