public class NumberedDFNode

extends DiscreteFunctionNode

implements NumericDiscreteNode

Numbered discrete function node. Each state of an NumberedDFNode represents a number.

Constructor Summary

NumberedDFNode(DiscreteFunctionNode node)
Constructs a new NumberedDFNode object corresponding to the given DiscreteFunctionNode object node.

NumberedDFNode(NetworkModel belongsTo)
Constructs a new NumberedDFNode.

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 NumberedDFNode.
void	setStateValue(long s, double v) Sets the value associated with a particular state of this NumberedDFNode.

Constructor Detail

NumberedDFNode

public NumberedDFNode(NetworkModel belongsTo)
               throws ExceptionHugin

Constructs a new NumberedDFNode.

NumberedDFNode

public NumberedDFNode(DiscreteFunctionNode node)
               throws ExceptionHugin

Constructs a new NumberedDFNode object corresponding to the given DiscreteFunctionNode object 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 NumberedDFNode.

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 NumberedDFNode.

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
