Class FromFile

  • All Implemented Interfaces:
    java.io.Serializable, OptionHandler, RevisionHandler

    public class FromFile
    extends SearchAlgorithm
    The FromFile reads the structure of a Bayes net from a file in BIFF format.

    Valid options are:

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

      • 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 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
