  - ### Method Detail

    - #### globalInfo

          public java.lang.String globalInfo()

      Returns a string describing this object
      Returns:
        a description of the classifier suitable for displaying in the explorer/experimenter gui

    - #### buildStructure

          public void buildStructure(BayesNet bayesNet,
                                     Instances instances)
                              throws java.lang.Exception

      Description copied from class: `SearchAlgorithm`
      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.
      Overrides:
        `buildStructure` in class `SearchAlgorithm`
      Parameters:
        `bayesNet` -
        `instances` - the instances to work with
      Throws:
        `java.lang.Exception` - if attribute from BIF file could not be found

    - #### setBIFFile

          public void setBIFFile(java.lang.String sBIFFile)

      Set name of network in BIF file to read structure from
      Parameters:
        `sBIFFile` - the name of the BIF file

    - #### getBIFFile

          public java.lang.String getBIFFile()

      Get name of network in BIF file to read structure from
      Returns:
        BIF file name

    - #### listOptions

          public java.util.Enumeration<Option> listOptions()

      Returns an enumeration describing the available options.
      Specified by:
        `listOptions` in interface `OptionHandler`
      Overrides:
        `listOptions` in class `SearchAlgorithm`
      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.

      Valid options are:

           -B <BIF File>
            Name of file containing network structure in BIF format

      Specified by:
        `setOptions` in interface `OptionHandler`
      Overrides:
        `setOptions` in class `SearchAlgorithm`
      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 search algorithm.
      Specified by:
        `getOptions` in interface `OptionHandler`
      Overrides:
        `getOptions` in class `SearchAlgorithm`
      Returns:
        an array of strings suitable for passing to setOptions

    - #### getRevision

          public java.lang.String getRevision()

      Returns the revision string.
      Specified by:
        `getRevision` in interface `RevisionHandler`
      Overrides:
        `getRevision` in class `SearchAlgorithm`
      Returns:
        the revision
