Method Detail

load

public BBNGraph load(java.io.InputStream r)
              throws ParseException

Specified by:

load in interface Converter

Throws:

ParseException

save

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

Specified by:

save in interface Converter

saveCPT

protected java.lang.String saveCPT(java.util.Hashtable valueListTable,
                                   java.util.Hashtable cpf,
                                   java.util.LinkedList nodes,
                                   java.util.Hashtable curQuery,
                                   java.lang.StringBuffer buf,
                                   java.lang.String filler)

Encode the flat-encoded CPF back into its nested String form. Dunno about the continuous chance node... It will break

Parameters:

valueListTable - A table of node name -> its value. If get method returns null, then it has no value (possibly a utility node).

cpf - The flat CPF we want to encode

nodes - The list of node names that has a role in the CPF encoding

curQuery - It is the Hashtable to form the query

buf - The string buffer for the output

filler - The string to pad the output (to beautify it)

Returns:

String The encoded string

saveProperty

protected java.lang.String saveProperty(java.util.Hashtable property,
                                        int filler)

getFiller

protected java.lang.String getFiller(int n)

initialize

public void initialize()

Specified by:

initialize in interface Converter

processGraph

protected BBNGraph processGraph(BBNGraph g)

formatCPF

protected java.util.Hashtable formatCPF(java.util.LinkedList valueList,
                                        java.util.LinkedList data,
                                        java.util.Hashtable queryValue,
                                        java.util.Hashtable input)

Reformat the list of lists into CPF

Parameters:

valueList - Basically list of node name and its value list

data - The data in multiply nested lists

queryValue - BBNQuery entry to be inputted

input - the resulting CPF, passed recursively while building

Returns:

Hashtable the CPF

resetCache

protected void resetCache()

This is to reset cache. Useful later if we decided to support OOBN.
