## weka.classifiers.bayes.net.search.fixed
Class FromFile

    java.lang.Object
      weka.classifiers.bayes.net.search.SearchAlgorithm
          weka.classifiers.bayes.net.search.fixed.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

Constructor Detail

### FromFile

    public FromFile()

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 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
