Class XMLBifParser

java.lang.Object
  edu.ksu.cis.bnj.bbn.converter.xmlbif.XMLBifParser

All Implemented Interfaces:

Converter

public class XMLBifParser

extends java.lang.Object

implements Converter

XMLBif 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:

Basically this is what Subbu and Prashanth did. However, I rewrite it.

Method Detail

initialize

public void initialize()

Specified by:

initialize in interface Converter

See Also:

Converter.initialize()

save

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

Save routine for XML BIF. Graph properties won't get saved. Node properties aren't either, except for the position.

Specified by:

save in interface Converter

See Also:

Converter.save(java.io.OutputStream, edu.ksu.cis.bnj.bbn.BBNGraph)

load

public BBNGraph load(java.io.InputStream stream)

Specified by:

load in interface Converter

See Also:

Converter.load(java.io.InputStream)

visitDocument

public void visitDocument(org.w3c.dom.Node parent)

visitModel

public void visitModel(org.w3c.dom.Node parent)

visitPRMClass

public PRMClass visitPRMClass(org.w3c.dom.Node parent)

visitPRMAttributeSet

protected void visitPRMAttributeSet(org.w3c.dom.Node parent,
                                    PRMClass prmClass)

visitVariable

protected BBNNode visitVariable(org.w3c.dom.Node parent)

parseProperty

protected void parseProperty(java.lang.String s,
                             java.util.Hashtable prop)

Parse string property. The input string is expected to have at least one equal sign. If the right hand side is enclosed with parentheses, it will treat it as lists. If the value is numeric, it tries to convert that to a Double. Otherwise, it stores the value as a string.

Parameters:

s - The property string

prop - The property table

visitDefinition

protected void visitDefinition(org.w3c.dom.Node parent)

getElementValue

protected java.lang.String getElementValue(org.w3c.dom.Node parent)

mangleXMLString

protected java.lang.String mangleXMLString(java.lang.String s)

Escape the string s to oblige to the XML rules (e.g.: "'" becomes ', "&" becomes &, and so on).

Parameters:

s - The raw string

Returns:

String The formatted string

main

public static void main(java.lang.String[] args)

Driver for testing this parser

Parameters:

args -

isRowFirst

public boolean isRowFirst()

Returns:

boolean

setRowFirst

public void setRowFirst(boolean rowFirst)

Sets the rowFirst.

Parameters:

rowFirst - The rowFirst to set
