All Implemented Interfaces:

Accessor, Decorable, Position, java.io.Serializable

Enclosing class:

NodeBinaryTree

protected static class NodeBinaryTree.NBTSuperNode

extends NodeBinaryTree.NBTNode

This is the supernode. There is one instance per tree, useful mainly so that container() calls can recur polymorphically up the tree Protected so subclasses can access it
