public class IntervalDFNode

extends DiscreteFunctionNode

implements NumericDiscreteNode

Interval discrete function node. Each state of an IntervalDFNode represents an interval.

Constructor Summary

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

IntervalDFNode(NetworkModel belongsTo)
Constructs a new IntervalDFNode.

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 (interval) matching the specified value.
double	getStateValue(long s) Returns the low value of the interval associated with state s.
void	setStateValue(long s, double v) Sets the low value of the interval associated with state s to v.

Constructor Detail

IntervalDFNode

public IntervalDFNode(NetworkModel belongsTo)
               throws ExceptionHugin

Constructs a new IntervalDFNode.

IntervalDFNode

public IntervalDFNode(DiscreteFunctionNode node)
               throws ExceptionHugin

Constructs a new IntervalDFNode 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 low value of the interval associated with state s. To indicate the right endpoint of the rightmost interval, specify s equal to the number of states of this IntervalDFNode.

Specified by:

getStateValue in interface NumericDiscreteNode

Parameters:

s - index of the state

Throws:

ExceptionHugin

getStateIndex

public long getStateIndex(double value)
                   throws ExceptionHugin

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

Specified by:

getStateIndex in interface NumericDiscreteNode

Parameters:

value - an interval containing this value will be searched for

Returns:

the index of the state (interval) containing the specified value.

Throws:

ExceptionHugin

setStateValue

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

Sets the low value of the interval associated with state s to v. To indicate the right endpoint of the rightmost interval, specify s equal to the number of states of this IntervalDFNode.

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
