A self-balancing binary tree optimised for fast access to frequently used nodes. Useful for implementing caches and garbage collection algorithms.
A unified interface to store and access persisted settings of tree-structured objects
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.
This gem implements a rooted, ordered tree, with a focus on easy iteration over nodes and access to basic tree properties. Moved to ---> "rooted".
PRX Access is a gem to supply authentication headers and descend the HAL hypermedia link tree on PRX's APIs.
System for accessing web services for tree-like things via the repl
A Splay Tree is a self adjusting binary search tree with the additional property that recently accessed elements are quick to access again. This makes it useful for caches because the most commonly accessed elements will be the fastest ones to access. This tree has an additional feature that allows it's maximum size to be restricted. When it exceeds it's maximum size, it will drop all of the nodes which are at the terminal ends of the tree structure, leaving many of the more commonly accessed nodes intact. This implementation is written in C++ with a Ruby wrapper.
Climbs the OWA tree. Ruby gem for getting information out Outlook Web Access
Builds trees of commands for the terminal, each node is either a group of commands or the command itself, every node is associated with a character to access it.
This gem implements a rooted, ordered tree, with a focus on easy iteration over nodes and access to basic tree properties. Formerly known as "rooted_tree".
Heimdall provides a mechanism to control access to features in your application. It uses a tree structure to represent feature flags and allows you to build and manage feature trees from templates. The library also includes access control checks to ensure that only authorized users can access certain features.
