Class Potential

java.lang.Object
  |
  +--ls.Potential

public class Potential

extends java.lang.Object

This class is responible for storing all of the cpt calculations that would make up the potential. This is used so that it can be easily determined of how one would go about calculation phi, based on individual attributes probabilities.

Constructor Summary

Potential()
Creates a new potential that has no cpt's associated with it.

Method Summary

void	add(CPT c) Adds a new cpt to the list.
void	addCB(java.lang.Object c) Sets one of the nodes that is used in computing the potential.
Potential	copy()
CPT	get(int index) Returns a particular cpt at a given location.
java.util.Vector	getCB()
Node	getCB(int index) Gets one of the nodes that is used in computing the potential.
void	setCB(java.util.Vector v)
void	setCPT(java.util.Vector v)
int	size() Returns the number of cpt's that are contianed within a particluar potential.

Constructor Detail

Potential

public Potential()

Creates a new potential that has no cpt's associated with it.

Method Detail

size

public int size()

Returns the number of cpt's that are contianed within a particluar potential. If the size = 0 then the potential value will equal 1.

Returns:

size - the number of cpt's that are used to calculate the potential

get

public CPT get(int index)

Returns a particular cpt at a given location.

Parameters:

index - the location of the cpt to be returned

Returns:

cpt - the cpt that the specified index

add

public void add(CPT c)

Adds a new cpt to the list. This results in another cpt that the potential for a clique needs to be mulitplied by to achive the actual potential.

Parameters:

c - the cpt to be added

getCB

public Node getCB(int index)

Gets one of the nodes that is used in computing the potential.

Returns:

one of the nodes in the potential

getCB

public java.util.Vector getCB()

addCB

public void addCB(java.lang.Object c)

Sets one of the nodes that is used in computing the potential.

Parameters:

cb - one of the nodes in the potential

copy

public Potential copy()

setCB

public void setCB(java.util.Vector v)

setCPT

public void setCPT(java.util.Vector v)
