Interface TreeNode

  • All Superinterfaces:
    java.lang.Cloneable, java.lang.Comparable, java.io.Serializable
    public interface TreeNode
extends java.lang.Cloneable, java.io.Serializable, java.lang.Comparable
    This interface defines a tree node for trace-out. The nodes of the tree can either be network nodes or virtual nodes on network links.
