NormalizerPMMLNodeModel

public NormalizerPMMLNodeModel()

Creates a new normalizer node model with an optional PMML inport and a PMML model outport.

Method Detail

prepareConfigure

protected PortObjectSpec[] prepareConfigure(PortObjectSpec[] inSpecs)
                                     throws InvalidSettingsException

Overrides:

prepareConfigure in class NormalizerNodeModel

Parameters:

inSpecs - An array of DataTableSpecs (as many as this model has inputs).

Returns:

An array of DataTableSpecs (as many as this model has outputs)

Throws:

InvalidSettingsException - if the #configure() failed, that is, the settings are inconsistent with given DataTableSpec elements.

execute

protected PortObject[] execute(PortObject[] inObjects,
                               ExecutionContext exec)
                        throws Exception

Execute method for general port types. The argument objects represent the input objects and are guaranteed to be subclasses of the PortObject classes that are defined through the PortTypes given in the constructor. Similarly, the returned output objects need to comply with their port types object class (otherwise an error is reported by the framework).

For a general description of the execute method refer to the description of the specialized NodeModel.execute(BufferedDataTable[], ExecutionContext) methods as it addresses more use cases.

Overrides:

execute in class NormalizerNodeModel

Parameters:

inObjects - The input objects.

exec - For BufferedDataTable creation and progress.

Returns:

The output objects.

Throws:

Exception - If the node execution fails for any reason.
