public class NameTree
extends Object

A PDF name tree consists of three kinds of nodes:

• The root node contains only a kids entry, pointing to many other objects
• An intermediate node contains the limits of all the children in its subtree, and a kids entry for each child
• A leaf node contains a set of name-to-object mappings in a dictionary, as well as the limits of the data contained in that child.

A PDF name tree is sorted in accordance with the String.compareTo() method.
