Overview

  • New

    • Bloom Filter

      - 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

    • Tries

      Map optimized for prefix searching on string keys

    • Multi-Valued

      Map supporting multiple values for a key

  • Queues

  • Utilities

    • LRU Cache with Stats

      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

      - An array of bits with operations to set, examine and clear individual bits

    • CircularBuffer

      - 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

      - Probabilistic data structure to test whether an element is a member of a set.

    • BTree

      - Self balancing generalized Search Tree

Installation
