The Kind class represents a classification of the Nodes of Classes and Domains.
public enum Node.Kind
The Kind tag indicates whether a node has a discrete or continuous state space (or something else).
This tag is used for continuous nodes. Continuous nodes represent random variables with Conditional Gaussian (CG) distributions. Only chance nodes can be continuous.
This tag is used for discrete nodes. Discrete nodes can assume values from a finite state space. Chance, decision, and function nodes can be discrete.
This tag is used for all other nodes. Utility, instance, and real-valued function nodes are included in this group.
