Method Detail

initialize

public void initialize()

Specified by:

initialize in interface Converter

load

public BBNGraph load(java.io.InputStream r)

Specified by:

load in interface Converter

save

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

We ignore properties in saving, except the position.

Specified by:

save in interface Converter

See Also:

Converter.save(OutputStream, BBNGraph)

processGraph

protected BBNGraph processGraph(BBNGraph g)

formatCPF

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

Reformat the list of lists into CPF

Parameters:

nodeList - Basically list of node name and its value list

data - The data in 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.
