(c) 2006, 2007 Anupam Sengupta
http://rubytree.rubyforge.org
Rubytree is a simple implementation of the generic Tree data structure. This
implementation is node-centric, where the individual nodes on the tree are the
primary objects and drive the structure.
== INSTALL:
Rubytree is an open source project and is hosted at:
http://rubytree.rubyforge.org
Rubytree can be downloaded as a Rubygem or as a tar/zip file from:
http://rubyforge.org/frs/?group_id=1215&release_id=8817
The file-name is one of:
rubytree-<VERSION>.gem - The Rubygem
rubytree-<VERSION>.tgz - GZipped source files
rubytree-<VERSION>.zip - Zipped source files
Download the appropriate file-type for your system.
It is recommended to install Rubytree as a Ruby Gem, as this is an easy way to
keep the version updated, and keep multiple versions of the library available on
your system.
=== Installing the Gem
To Install the Gem, from a Terminal/CLI command prompt, issue the command:
gem install rubytree
This should install the gem file for Rubytree. Note that you may need to be a
super-user (root) to successfully install the gem.
=== Installing from the tgz/zip file
Extract the archive file (tgz or zip) and run the following command from the
top-level source directory:
ruby ./setup.rb
You may need administrator/super-user privileges to complete the setup using
this method.
== DOCUMENTATION:
The primary class for this implementation is Tree::TreeNode. See the
class documentation for an usage example.
From a command line/terminal prompt, you can issue the following command to view
the text mode ri documentation:
ri Tree::TreeNode
Documentation on the web is available at:
http://rubytree.rubyforge.org/rdoc
== EXAMPLE:
The following code-snippet implements this tree structure:
+------------+
| ROOT |
+-----+------+
+-------------+------------+
| |
+-------+-------+ +-------+-------+
| CHILD 1 | | CHILD 2 |
+-------+-------+ +---------------+
|
|
+-------+-------+
| GRANDCHILD 1 |
+---------------+
require 'tree'
myTreeRoot = Tree::TreeNode.new("ROOT", "Root Content")
myTreeRoot << Tree::TreeNode.new("CHILD1", "Child1 Content") << Tree::TreeNode.new("GRANDCHILD1", "GrandChild1 Content")
myTreeRoot << Tree::TreeNode.new("CHILD2", "Child2 Content")
myTreeRoot.printTree
child1 = myTreeRoot["CHILD1"]
grandChild1 = myTreeRoot["CHILD1"]["GRANDCHILD1"]
siblingsOfChild1Array = child1.siblings
immediateChildrenArray = myTreeRoot.children
# Process all nodes
myTreeRoot.each { |node| node.content.reverse }
myTreeRoot.remove!(child1) # Remove the child

# This module provides a TreeNode class which is the primary class for all
# nodes represented in the Tree.
# This module mixes in the Enumerable module.
module Tree
# Rubytree Package Version
VERSION = '0.5.2'
# == TreeNode Class Description
#
# The node class for the tree representation. the nodes are named and have a
# place-holder for the node data (i.e., the `content' of the node). The node
# names are expected to be unique. In addition, the node provides navigation
# methods to traverse the tree.
#
# The nodes can have any number of child nodes attached to it. Note that while
# this implementation does not support directed graphs, the class itself makes
# no restrictions on associating a node's CONTENT with multiple parent nodes.
#
#
# == Example
#
# The following code-snippet implements this tree structure:
#
# +------------+
# | ROOT |
# +-----+------+
# +-------------+------------+
# | |
# +-------+-------+ +-------+-------+
# | CHILD 1 | | CHILD 2 |
# +-------+-------+ +---------------+
# |
# |
# +-------+-------+
# | GRANDCHILD 1 |
# +---------------+
#
# require 'tree'
#
# myTreeRoot = Tree::TreeNode.new("ROOT", "Root Content")
#
# myTreeRoot << Tree::TreeNode.new("CHILD1", "Child1 Content") << Tree::TreeNode.new("GRANDCHILD1", "GrandChild1 Content")
#
# myTreeRoot << Tree::TreeNode.new("CHILD2", "Child2 Content")
#
# myTreeRoot.printTree
#
# child1 = myTreeRoot["CHILD1"]
#
# grandChild1 = myTreeRoot["CHILD1"]["GRANDCHILD1"]
#
# siblingsOfChild1Array = child1.siblings
#
# immediateChildrenArray = myTreeRoot.children
#
# # Process all nodes
#
# myTreeRoot.each { |node| node.content.reverse }
#
# myTreeRoot.remove!(child1) # Remove the child
class TreeNode
