A random variable that serves as a node in a Bayes net (directed graphical model). 


public interface BayesNetVar {
Returns true if the given world is complete enough to determine the value of this random variable. 


    boolean isDetermined(PartialWorld w);
Returns the value of this random variable in the given world. complete enough to determine the value of this variable

Throws:  IllegalArgumentException if the given partial world is not 


    Object getValue(PartialWorld w);
Returns the set of parents of this variable in the given partial world. The parents are those random variables which, if they changed, could change the probability of this variable having a given value. This method yields a fatal error if the partial world is not complete enough to determine this variable's parents.

Returns:  Set of BayesNetVar 


    Set getParents(PartialWorld w);
Returns the first parent of this variable that is uninstantiated in the given partial world. This method uses a decision tree view of the variable's CPD; it walks down the tree until it reaches a node corresponding to an uninstantiated variable. If all of this variable's active parents in the given partial world are instantiated, then this method returns null. 


    BasicVar getFirstUninstParent(PartialWorld w);
Ensures that the partial world underlying the given InstantiatingEvalContext is complete enough to determine the value of this variable and to determine its probability distribution conditional on its parents. 


    void ensureDetAndSupported(InstantiatingEvalContext instantiator);
Returns the timestep that this variable is associated with, or null if it is atemporal. 


    Timestep timestep();
}
