Method Detail

configure

public void configure(Configuration configuration)

Description copied from class: ModelEvaluator

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.

Overrides:

configure in class ModelEvaluator<org.dmg.pmml.mining.MiningModel>

getSummary

public String getSummary()

Description copied from interface: Evaluator

Gets a short description of the Model.

Specified by:

getSummary in interface Evaluator

getDataField

protected org.dmg.pmml.DataField getDataField()

Overrides:

getDataField in class ModelEvaluator<org.dmg.pmml.mining.MiningModel>

Returns:

A synthetic DataField element describing the default target field.

isPure

public boolean isPure()

Description copied from class: ModelEvaluator

Indicates if this model evaluator represents a pure function.

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

Overrides:

isPure in class ModelEvaluator<org.dmg.pmml.mining.MiningModel>

getTargetName

public org.dmg.pmml.FieldName getTargetName()

Overrides:

getTargetName in class ModelEvaluator<org.dmg.pmml.mining.MiningModel>

getEntityRegistry

public com.google.common.collect.BiMap<String,org.dmg.pmml.mining.Segment> getEntityRegistry()

Specified by:

getEntityRegistry in interface HasEntityRegistry<org.dmg.pmml.mining.Segment>

Returns:

A bidirectional map between Entity identifiers and Entity instances.

createOutputFields
