public static class IloCplex.NodeId
extends java.lang.Object

A class for uniquely identifying a MIP node in a branch-and-cut tree.

IloCplex assigns a NodeId to every node it creates. In fact, the NodeId of a node created with one of the IloCplex.BranchCallback.makeBranch methods is returned by these methods.

The NodeId of the current node can be queried from a goal or from a callback that is called at a node. The IloCplex.NodeCallback allows you to access the NodeId of all remaining nodes.
