RubyTree is a Ruby implementation of the generic tree data structure. It provides simple APIs to store named nodes, and to access, modify, and traverse the tree. The data model is node-centric, where nodes in the tree are the primary structural elements. It supports all common tree-traversal methods (pre-order, post-order, and breadth first). RubyTree mixes in the Enumerable and Comparable modules and behaves like a standard Ruby collection (iteration, comparison, etc.). RubyTree also includes a binary tree implementation, which provides in-order node traversal besides the other methods. RubyTree can import from and export to JSON, and supports Ruby’s object marshaling.
