public class AVLTree.Node extends Object
This class implements AVL trees nodes.AVL tree nodes implement all the logical structure of the tree. Nodes are created by the
AVLTree
class.The nodes are not independant from each other but must obey specific balancing constraints and the tree structure is rearranged as elements are inserted or deleted from the tree. The creation, modification and tree-related navigation methods have therefore restricted access. Only the order-related navigation, reading and delete methods are public.
