  extended byCOM.hugin.HAPI.Model

public class Model
extends java.lang.Object

A Model is a compact description of a table. A model consists of a list of discrete nodes and a set of expressions (one expression per configuration of states of the nodes.

Constructor Detail

Model

public Model(Node belongsTo,
             NodeList modelNodes)
      throws ExceptionHugin
Constructs a model over a node given a list of Nodes.

Method Detail

delete

public void delete()
            throws ExceptionHugin
Deletes this Model.

Throws:
ExceptionHugin

getNodes

public NodeList getNodes()
                  throws ExceptionHugin
Returns a NodeList containing the Nodes in this Model.

Throws:
ExceptionHugin

getSize

public int getSize()
            throws ExceptionHugin
Returns the number of configurations of the Nodes of this Model.

Throws:
ExceptionHugin

setExpression

public void setExpression(int index,
                          Expression expression)
                   throws ExceptionHugin
Associates an Expression with a specific configuration of the Nodes of this Model.

Throws:
ExceptionHugin

setExpression

public void setExpression(int index,
                          java.lang.String expression,
                          ParseListener parseListener)
                   throws ExceptionHugin
Associates an expression (specified as a String) with a specific configuration of the Nodes of this Model.

Throws:
ExceptionHugin

getExpression

public Expression getExpression(int index)
                         throws ExceptionHugin
Returns the Expression associated with a specific configuration of the Nodes of this Model.

Throws:
ExceptionHugin

setNumberOfSamplesPerInterval

public void setNumberOfSamplesPerInterval(int count)
                                   throws ExceptionHugin
Sets the number of values taken within each bounded interval of an interval parent when generating the conditional probability table for a node with interval parents.

When generating the conditional probability table for a node with interval nodes as parents, a number of values are taken within each bounded interval of an interval parent. By default, the interval is divided into 25 subintervals, and the midpoints of these subintervals are then used in the computation of the value of the child.

Parameters:
count - the number of subintervals.
Throws:
ExceptionHugin

getNumberOfSamplesPerInterval

public int getNumberOfSamplesPerInterval()
                                  throws ExceptionHugin
Returns the number of values per interval used when generating the conditional probability table for a node with interval parents.

Returns:
An integer.
Throws:
ExceptionHugin

isAlive

public boolean isAlive()
Is this Model object alive?
