| node_bn* NewNode_bn ( | const char* name, int num_states, net_bn* net ) |
Creates and returns a new node for net.
If the node is for a discrete variable, pass the number of states it has for num_states.
If the node is for a variable which is continuous in the real world, pass 0 for num_states, even if you plan to later discretize it to a certain number of states (see SetNodeLevels_bn for more details).
name will be the name of the new node. It must be different from the names of all other nodes in net (by case-sensitive comparison), and it must be a legal IDname, which means it must have NAME_MAX_ns (30) or fewer characters, all of which are letters, digits or underscores, and it must start with a letter. If name ends with an asterisk (*), then Netica will replace the * with an integer to make a unique name for the node; you can discover what name was picked using GetNodeName_bn after the node is formed.
The node will start off as a nature node (kind = NATURE_NODE), but it may be changed by calling SetNodeKind_bn.
Netica will make a copy of name; it won't modify or free the passed string.
