Method Detail

prepare

public Object prepare(FieldName name,
                      String string)

Description copied from interface: Evaluator

Prepares the input value for a field

Specified by:

prepare in interface Evaluator

Parameters:

name - The name of the field

string - The String representation of the input value. Use null to represent missing input value.

Consumer.getDataField(FieldName), Consumer.getMiningField(FieldName)

evaluate

public Map<FieldName,?> evaluate(Map<FieldName,?> parameters)

Specified by:

evaluate in interface Evaluator

Parameters:

parameters - Map of active field values.

Returns:

Map of predicted field and output field values. Simple values are represented using the Java equivalents of PMML data types (eg. String, Integer, Float, Double etc.). Complex values are represented as instances of Computable that return simple values.
