The tree structure \ is not an object itself, but is emergent from the linkages \ you create between nodes. This class provides the methods \ for making linkages that can be used to build up a tree, \ while preventing you from ever making any kinds of \ linkages which are not allowed in a tree (such as having \ a node be its own mother or ancestor, or having a node \ have two mothers). platforms darwin checksums md5 3b006f128bd1d8961fc57c466ffa05f2
