public class NumberedDDNode

extends DiscreteDecisionNode

implements NumericDiscreteNode

Numbered discrete decision node. Each state of an NumberedDDNode represents a number.

Constructor Summary

NumberedDDNode(DiscreteNode node)
Constructs a new NumberedDDNode object corresponding to the given DiscreteNode object node.

NumberedDDNode(NetworkModel belongsTo)
Constructs a new NumberedDDNode.

Method Summary

double	getQuantile(double probability) Returns the quantile corresponding to the specified probability argument of the inverse cumulative distribution function.
long	getStateIndex(double value) Returns the index of the state matching the specified value.
double	getStateValue(long s) Returns the value associated with a particular state of this NumberedDDNode.
void	setStateValue(long s, double v) Sets the value associated with a particular state of this NumberedDDNode.

Constructor Detail

NumberedDDNode

public NumberedDDNode(NetworkModel belongsTo)
               throws ExceptionHugin

Constructs a new NumberedDDNode.

NumberedDDNode

public NumberedDDNode(DiscreteNode node)
               throws ExceptionHugin

Constructs a new NumberedDDNode object corresponding to the given DiscreteNode object node. (node must be a chance or a decision node.) The new object will be identical to node (that is, same parents, same table, etc.) except for its type.

As a side-effect, the object node dies (that is, becomes "not-alive"). Moreover, all (output and temporal) clones associated with node also die.

Method Detail

getStateValue

public double getStateValue(long s)
                     throws ExceptionHugin

Returns the value associated with a particular state of this NumberedDDNode.

Specified by:

getStateValue in interface NumericDiscreteNode

Parameters:

s - the index of the state in question.

Throws:

ExceptionHugin

getStateIndex

public long getStateIndex(double value)
                   throws ExceptionHugin

Returns the index of the state matching the specified value. If there is no (unique) state with the specified state value, -1 is returned.

Specified by:

getStateIndex in interface NumericDiscreteNode

Parameters:

value - the state value of the state to be searched for

Returns:

the index of the state with the specified state value.

Throws:

ExceptionHugin

setStateValue

public void setStateValue(long s,
                          double v)
                   throws ExceptionHugin

Sets the value associated with a particular state of this NumberedDDNode.

Specified by:

setStateValue in interface NumericDiscreteNode

Parameters:

s - the index of the state in question.

v - the new value for state s.

Throws:

ExceptionHugin

getQuantile

public double getQuantile(double probability)
                   throws ExceptionHugin

Returns the quantile corresponding to the specified probability argument of the inverse cumulative distribution function.

Specified by:

getQuantile in interface NumericDiscreteNode

Throws:

ExceptionHugin
