        Returns:
        the name of the creating application or null if not specified in the pmml.
      • setLog

        public void setLog​(Logger log)
        Set a logger to use.
        Specified by:
        setLog in interface PMMLModel

      • buildClassifier

        public void buildClassifier​(Instances data)
                             throws java.lang.Exception
        Throw an exception - PMML models are pre-built.
        Specified by:
        buildClassifier in class Classifier
        Parameters:
        data - the Instances to learn from
        Throws:
        java.lang.Exception - if something goes wrong
      • done

        public void done()
        Signal that a scoring run has been completed. Resets the initialized state to false so that a subsequent scoring run will trigger the mapping of the mining schema to incoming instances. If not called after a scoring run, then the classifier will assume that the current mapping is still valid.
      • mapToMiningSchema

        public void mapToMiningSchema​(Instances dataSet)
                               throws java.lang.Exception
        Map mining schema to incoming instances.
        Parameters:
        dataSet - the structure of the incoming Instances
        Throws:
        java.lang.Exception - if something goes wrong
      • getFieldsMappingString

        public java.lang.String getFieldsMappingString()
        Get a textual description of the mapping between mining schema fields and incoming data fields.
        Returns:
        a description of the fields mapping as a String or null if no mapping has been constructed yet.
