      • listOptions

        public java.util.Enumeration listOptions()
        Returns an enumeration describing the available options.
        Specified by:
        listOptions in interface OptionHandler
        Returns:
        an enumeration of all the available options.

      • setOptions

        public void setOptions​(java.lang.String[] options)
                throws java.lang.Exception
        Parses a given list of options.

        Specified by:
        setOptions in interface OptionHandler
        Parameters:
        options - the list of options as an array of strings
        Throws:
        java.lang.Exception - if an option is not supported

      • getOptions

        public java.lang.String[] getOptions()
        Gets the current settings of the Classifier.
        Specified by:
        getOptions in interface OptionHandler
        Returns:
        an array of strings suitable for passing to setOptions

      • toString

        public java.lang.String toString()
        a string representation of the algorithm
        Overrides:
        toString in class java.lang.Object
        Returns:
        a string representation

      • buildStructure

        public void buildStructure​(BayesNet bayesNet,
                           Instances instances)
                    throws java.lang.Exception
        buildStructure determines the network structure/graph of the network. The default behavior is creating a network where all nodes have the first node as its parent (i.e., a BayesNet that behaves like a naive Bayes classifier). This method can be overridden by derived classes to restrict the class of network structures that are acceptable.
        Parameters:
        bayesNet - the network
        instances - the data to use
        Throws:
        java.lang.Exception - if something goes wrong

      • maxNrOfParentsTipText

        public java.lang.String maxNrOfParentsTipText()
        Returns:
        a string to describe the MaxNrOfParentsoption.

      • initAsNaiveBayesTipText

        public java.lang.String initAsNaiveBayesTipText()
        Returns:
        a string to describe the InitAsNaiveBayes option.

      • getRevision

        public java.lang.String getRevision()
        Returns the revision string.
        Specified by:
        getRevision in interface RevisionHandler
        Returns:
        the revision
