=======================================

This is a collection of different data structures and utilities, implemented in JavaScript.

Its written and tested using Node.js which is also the target platform.



### [API Documentation >>](http://monmohan.github.io/dsjslib)



Overview

----------------

* New

    * [Bloom Filter](http://monmohan.github.io/dsjslib/BloomFilter.html) - Probabilistic data structure to test whether an element is a member of a set.



* Maps

    * Sorted Maps:  Maps sorted according to natural ordering of keys or by comparator function provided at creation time.

    Two different backing stores are available

        * [AVLTree](http://monmohan.github.io/dsjslib/AVLTree.html)

        * [Skip List](http://monmohan.github.io/dsjslib/SkipList.html)

    * Tries Map optimized for prefix searching on string keys

        * [Multi Way Trie](http://monmohan.github.io/dsjslib/RWayTrie.html)

        * [Ternary Search Trie](http://monmohan.github.io/dsjslib/TernarySearchTrie.html)

    * Multi-Valued Map supporting multiple values for a key

        * [MultiMap](http://monmohan.github.io/dsjslib/MultiMap.html)

        * [TreeMultiMap](http://monmohan.github.io/dsjslib/TreeMultiMap.html) - In addition, Map is sorted on keys. Uses AVLTree as backing store

* Queues

    * [Linked Deque](http://monmohan.github.io/dsjslib/LinkedDeque.html) - An optionally capacity constrained deque based on linked nodes

    * [Priority Queue](http://monmohan.github.io/dsjslib/PriorityQueue.html) - Priority Queue based on a Binary Heap

    * [Delay Queue](http://monmohan.github.io/dsjslib/DelayQueue.html) - Queue of 'Delayed' items, item can only be taken when its delay has expired.

        For example usage see [wiki: DelayQueue-for-Scheduled-Task-Management](https://github.com/monmohan/dsjslib/wiki/Example:-DelayQueue-for-Scheduled-Task-Management)



* Utilities

    * [LRU Cache with Stats](http://monmohan.github.io/dsjslib/Cache.html) Google Guava inspired LRU cache. [Reference: Google Guava](https://code.google.com/p/guava-libraries/). In-memory LRU cache implementation for Node,

    inspired by Google Guava Loading Cache .  The cache is simpler since it doesn't have to deal with concurrent threads, but other functionality of Guava

    cache are captured like

           - Auto loader function

           - Removal listener

           - Auto expiry After Write (TTL)

           - Max Size and weight

           - Cache Stats recording

    For usage and overview see wiki: https://github.com/monmohan/dsjslib/wiki/LRU-Cache-Feature-and-usage-overview



    * [BitSet](http://monmohan.github.io/dsjslib/BitSet.html) - An array of bits with operations to set, examine and clear individual bits

    * [CircularBuffer](http://monmohan.github.io/dsjslib/CircularBuffer.html) - A data structure that uses a single, fixed-size buffer as if it were connected end-to-end.

    When the buffer is filled, new data is written starting at the beginning of the buffer and overwriting the old.

    * [Bloom Filter](http://monmohan.github.io/dsjslib/BloomFilter.html) - Probabilistic data structure to test whether an element is a member of a set.

    * [BTree](http://monmohan.github.io/dsjslib/BTree.html) - Self balancing generalized Search Tree
