Class PMMLContentHandler

java.lang.Object
  org.xml.sax.helpers.DefaultHandler
      org.knime.core.node.port.pmml.PMMLContentHandler

All Implemented Interfaces:

ContentHandler, DTDHandler, EntityResolver, ErrorHandler

Direct Known Subclasses:

PMMLAssociationRuleHandler, PMMLDiscretizeBinContentHandler, PMMLDiscretizeContentHandler, PMMLIntervalContentHandler, PMMLPreprocDiscretize.PMMLPreprocDiscretizeContentHandler

Deprecated.

@Deprecated
public abstract class PMMLContentHandler
extends DefaultHandler
implements ContentHandler

This class should no longer be used. PMML support is handled now with the help of XMLBeans. A PMMLTranslator should be implemented to provide the translation from PMML to KNIME and vice versa.

canReadPMMLVersion

public boolean canReadPMMLVersion(String version)

Deprecated.

Checks whether the PMML version is supported.

Parameters:

version - The PMML version to be tested.

Returns:

True if the handler can read the specified version, false otherwise

getSupportedVersions

protected Set<String> getSupportedVersions()

Deprecated.

Returns the supported PMML versions. Override this method in a derived class to change the set of supported versions. Versions are e.g. PMMLPortObject.PMML_V3_1 or PMMLPortObject.PMML_V3_2.

Returns:

A set of the PMML version supported by this PMML port object.

getPreferredWriteVersion

protected String getPreferredWriteVersion()

Deprecated.

Returns the PMML version that this content handler prefers to write. Override this method in a derived class to change the set preferred version. Valid versions are defined in PMMLPortObject#getSupportedPMMLVersions().

Returns:

the preferred PMML version

parse

public void parse(Node node)
           throws SAXException

Deprecated.

Parses the given node.

Parameters:

node - the node to be parsed

Throws:

SAXException - if something with the parsing goes wrong

addPMMLModel

public final void addPMMLModel(DocumentFragment fragment,
                               PMMLPortObjectSpec spec)
                        throws SAXException

Deprecated.

Parameters:

fragment - the document fragment to add the model to

spec - the pmml port object spec

Throws:

SAXException - if the model cannot be added

getPMMLModelFragment

public final ByteArrayInputStream getPMMLModelFragment(PMMLPortObjectSpec spec)
                                                throws SAXException

Deprecated.

Parameters:

spec - the pmml port object spec

Returns:

an input stream containing the model fragment

Throws:

SAXException - if the model cannot be added

addPMMLModelContent

protected void addPMMLModelContent(TransformerHandler handler,
                                   PMMLPortObjectSpec spec)
                            throws SAXException

Deprecated.

Derived classes should override this method to add the model content. They can assume that the document is started and will be ended and should only provided the content starting with the mining scheme. If they want to support the addition of LocalTransformations they have to provide an empty element that can be filled later with preprocessing operations.

Parameters:

handler - the transformer handler

spec - the port object spec

Throws:

SAXException - if the model cannot be added
