Class FileIO

  +--xbneditor.FileIO

public class FileIO

extends java.lang.Object

This class is responsible for the reading and writing of the Bayesian Networks to disk. It reads them in in the BNIF 0.13 format and then will put them in the corresponding data structure so that the network can be manipulated. Fix the bug for bif file format , and extend it to Genie(.dsl) and Hugin(.net) format on Friday, Nov. 02, 2001 Now it can load .xml, .bif, .dsl and .net file format; it can save to .xml and .bif format Updated on Wednesday, Nov. 07, 2001 --> now it can load 6 BBN formats: .bif, .xml, .xbn, .dsc, .dsl, .net Updated on Thursday, Nov. 08, 2001 --> now it can load 2 more BBN formats: .dnet, .ent

Constructor Summary

Constructor Detail

FileIO

public FileIO()

The constructor for the Bayesian Network class. It will provide the functionality to load a Bayesian Network from disk or to save a newly created or modified Bayesian Network.

Method Detail

save

public void save(java.lang.String filename,
                 java.util.LinkedList baynet)

This function takes in a Bayesian Network that has already been created and will then save it to disk. It will save it to the file format that the user has specified.

Parameters:

filename - the file that this network is being saved to

baynet - the Bayesian Network that needs to be saved

convert

public void convert(java.lang.String outputfilename,
                    java.util.LinkedList baynet,
                    java.lang.String outputfiletype)

This function takes in a Bayesian Network that has already been created and will then save it to disk. It will save it to the file format that the user has specified.

Parameters:

filename - the file that this network is being saved to

baynet - the Bayesian Network that needs to be saved

load

public java.util.LinkedList load(java.lang.String filename)

This function loads a specific file into the editor. It determines what file type has been picked and then it will direct it to the appropriate functions that need to be called.

Parameters:

filename - the name of the file that contains the Bayesian Network that needs to be loaded

Returns:

baynet the Bayesian Network that was read in from the file

setFileType

public void setFileType(java.lang.String type)

Sets the current type of file that is being used. This is useful when a file is being imported to the editor.

Parameters:

type - the type of the file

getFileType

public java.lang.String getFileType()

Returns the current type of file that is being used to save the Bayesian network status

Returns:

currenttype - the current type of the file
