ModelEvaluator

ModelEvaluator

protected ModelEvaluator(org.dmg.pmml.PMML pmml,
                         M model)

Method Detail

configure

public void configure(Configuration configuration)

Configures the runtime behaviour of this model evaluator.

Must be called once before the first evaluation. May be called any number of times between subsequent evaluations.

isParentCompatible

public boolean isParentCompatible()

Indicates if this model evaluator is compatible with its parent model evaluator.

A parent compatible model evaluator inherits DataField declarations unchanged, which makes it possible to propagate DataField and global DerivedField values between evaluation contexts during evaluation.

isPure

public boolean isPure()

Indicates if this model evaluator represents a pure function.

A pure model evaluator does not tamper with the evaluation context during evaluation.

getNumberOfVisibleFields

protected int getNumberOfVisibleFields()

verify

public ModelEvaluator<M> verify()

Description copied from interface: Evaluator

Verifies the model.

Specified by:

verify in interface Evaluator

createEvaluationContext

public ModelEvaluationContext createEvaluationContext()

evaluate

public Map<org.dmg.pmml.FieldName,?> evaluate(Map<org.dmg.pmml.FieldName,?> arguments)

Description copied from interface: Evaluator

Evaluates the model with the specified arguments.

Specified by:

evaluate in interface Evaluator

Parameters:

arguments - Map of input field values.

Returns:

Map of target field and output field values. A target field could be mapped to a complex value or a simple value. An output field is always mapped to a simple value. Complex values are represented as instances of Computable that return simple values. Simple values are represented using the Java equivalents of PMML data types (eg. String, Integer, Float, Double etc.). A missing value is represented by null.
