PMMLAssociationRuleHandler

public PMMLAssociationRuleHandler()

Deprecated.

Creates a new empty association rule handler. The initialization has to be performed by registering the handler to a parser.

PMMLAssociationRuleHandler

public PMMLAssociationRuleHandler(int nrOfTransactions,
                                  double minSupport,
                                  double minConfidence,

                                  Set<AssociationRule> rules)

Deprecated.

Creates an initialized association rule handler that can be used to output the association rule model by invoking PMMLContentHandler.addPMMLModel(org.w3c.dom.DocumentFragment, PMMLPortObjectSpec).

Parameters:

nrOfTransactions - the number of transactions

minSupport - the minimum support

minConfidence - the minimum confidence

items - the items

itemsets - the itemsets

rules - the association rules

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.

Overrides:

addPMMLModelContent in class PMMLContentHandler

Parameters:

handler - the transformer handler

spec - the port object spec

Throws:

SAXException - if the model cannot be added
