Class XBNParser

java.lang.Object
  edu.ksu.cis.bnj.bbn.converter.xbn.XBNParser

All Implemented Interfaces:

Converter

public class XBNParser

extends java.lang.Object

implements Converter

Microsoft XBN Parser

Description:

This class is used to parse XML data given in the form of a file (see constructor) and add the data into the BNJ nodes. It also adds probability to the child nodes. This is a DOM implementation

TO DO:

• Continuous chance / distribution
• Shared distribution (esp. in OOBN)
• This format need to be extended to handle utility/decision nodes

Version:

0.1.0

Method Detail

initialize

public void initialize()

Specified by:

initialize in interface Converter

See Also:

Converter.initialize()

load

public BBNGraph load(java.io.InputStream stream)

Specified by:

load in interface Converter

See Also:

edu.ksu.cis.bnj.bbn.converter.Converter#load(java.io.Reader)

save

public void save(java.io.OutputStream stream,
                 BBNGraph graph)

This routine is supposed to save the BBN Graph into MS XBN format. Currently, I decided to scrap all of the properties. Maybe I'll add them later. Also, I don't rebuild through XML, since we're only interested in storing the contents, not actually converting it to XML.

Specified by:

save in interface Converter
