Subject: [Rubytree-users] Initializing a Binary Tree
Message-ID: <B59920F5-5645-460A-9808-9498EB288BF9@gmail.com>

Hello Everyone

I'm trying to use the rubytree gem for a school project. I managed to get it working in general, but I can't initialize a binary tree.

For Example, the following cod works well:

require 'rubygems'
require 'tree'
root_node = Tree::TreeNode.new("ROOT", "Root Content")
root_node.print_tree

Now my question is, shouldn't the following code work for a binary tree, or am I wrong?

require 'rubygems'
require 'tree'
root_node = Tree::BinaryTreeNode.new("ROOT", "Root Content")

On this line, it returns the following:

NameError: uninitialized constant Tree::BinaryTreeNode
	from (irb):6


I use the following setup, if thats any help: 

$ gem list --local
*** LOCAL GEMS ***

rubytree (0.8.1)


$ ruby -v
ruby 1.8.7 (2009-06-12 patchlevel 174) [i686-darwin10]

$ gem -v
1.3.4

The OS is Mac OS 10.6.4.

I hope, someone can give me a hint. 

Johannes

You also need `require 'tree/binarytree'` (checked on 0.7.0).

Thank you very much, that works also in version 0.8.1 and solved the problem.
