Numbered discrete chance node. Each state of an NumberedDCNode represents a number.


Constructor Summary
NumberedDCNode(DiscreteNode node)
          Constructs a new NumberedDCNode object corresponding to the given DiscreteNode object node.
NumberedDCNode(NetworkModel belongsTo)
          Constructs a new NumberedDCNode.
 
Method Summary
 double getQuantile(double probability)
          Returns the quantile corresponding to the specified probability argument of the inverse cumulative distribution function.
 int getStateIndex(double value)
          Returns the index of the state matching the specified value.
 double getStateValue(int s)
          Returns the value associated with a particular state of this NumberedDCNode.
 void setStateValue(int s, double v)
          Sets the value associated with a particular state of this NumberedDCNode.

Constructor Detail

NumberedDCNode

public NumberedDCNode(NetworkModel belongsTo)
               throws ExceptionHugin
Constructs a new NumberedDCNode.

Throws:
ExceptionHugin

NumberedDCNode

public NumberedDCNode(DiscreteNode node)
               throws ExceptionHugin
Constructs a new NumberedDCNode 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.

Throws:
ExceptionHugin
Method Detail

getStateValue

public double getStateValue(int s)
                     throws ExceptionHugin
Returns the value associated with a particular state of this NumberedDCNode.

Specified by:
getStateValue in interface NumericDiscreteNode
Parameters:
s - the index of the state in question.
Throws:
ExceptionHugin

getStateIndex

public int 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(int s,
                          double v)
                   throws ExceptionHugin
Sets the value associated with a particular state of this NumberedDCNode.

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
