com.pervasive.datarush.analytics.pmml.PMMLPort

public final class PMMLPort
extends AbstractModelPort<PMMLModel>

Specialization of model ports for handling PMML models. Like model ports, the PMML model is duplicated to parallel downstream nodes when transmitted from a non-parallel node. (This would be a typical "predictor" scenario where a copy of a a model is used to predict in all data partitions). Similarly, when transmitted from parallel to non-parallel a gather is performed and thus a merge handler must be specified.

FACTORY

public static final AbstractModelPortFactory<PMMLModel,PMMLPort> FACTORY

A factory for PMML ports.

Method Details

getFactory

public AbstractModelPortFactory<PMMLModel,PMMLPort> getFactory()

Description copied from class: LogicalPort

Returns the factory that knows how to create ports of this type

Specified by:

getFactory in class AbstractModelPort<PMMLModel>

Returns:

the factory that knows how to create ports of this type

setPMMLModelSpec

public void setPMMLModelSpec(MetadataCalculationContext ctx,
 PMMLModelSpec spec)

Setter to be used to set the PMMLModelSpec for PMML ports.

Parameters:

ctx - the metadata context

spec - the PMMLModelSpec; may be null in which case we declare metadata to be dynamic

getPMMLModelSpec

public PMMLModelSpec getPMMLModelSpec(MetadataContext ctx)

Getter to be used to set the PMMLModelSpec for a PMMLPort

Parameters:

ctx - the metadata context

Returns:

the PMMLModelSpec

getMetadata

public PMMLPort.Metadata getMetadata(PMMLModel model)

Description copied from class: AbstractModelPort

Returns the metadata associate with the model. (Given a model, we should always be able to get its metadata.

Specified by:

getMetadata in class AbstractModelPort<PMMLModel>

Parameters:

model - the model object

Returns:

the metadata

getMetadataType

public Class<? extends PortMetadata> getMetadataType()

Description copied from class: LogicalPort

Returns the class of metadata that this port uses

Specified by:

getMetadataType in class LogicalPort

Returns:

the class of metadata that this port uses
