### FromFile

Method Detail

### 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`
  Throws:
    `java.lang.Exception`

### setBIFFile

    public void setBIFFile(java.lang.String sBIFFile)

  Set name of network in BIF file to read structure from

  Parameters:
    `sBIFFile` -

### 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 Set the random order to true (default false).

  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
