DashMap
Blazing fast concurrent HashMap for Rust
Blazingly fast concurrent map in Rust. DashMap is an implementation of a concurrent associative array/hashmap in Rust. DashMap tries to implement an easy-to-use API similar to std::collections::HashMap with some slight changes to handle concurrency. DashMap tries to be very simple to use and to be a direct replacement for RwLock<HashMap<K, V>>. To accomplish these goals, all methods take &self instead of modifying methods taking &mut self. -

DataScript
Immutable database and Datalog query engine for Clojure, ClojureScript
...You create a database on page load, put some data in it, track changes, do queries and forget about it when the user closes the page. DataScript databases are immutable and based on persistent data structures. In fact, they’re more like data structures than databases (think Hashmap). Unlike querying a real SQL DB, when you query DataScript, it all comes down to a Hashmap lookup. Or series of lookups. Or array iteration. There’s no particular overhead to it. You put a little data in it, it’s fast. You put in a lot of data, well, at least it has indexes. That should do better than you filtering an array by hand anyway. ... -

go-datastructures
A collection of useful, performant, and threadsafe Go datastructures
Go-datastructures is a collection of useful, performant, and threadsafe Go datastructures. Interval tree for collision in n-dimensional ranges. Implemented via a red-black augmented tree. Extra dimensions are handled in simultaneous inserts/queries to save space although this may result in suboptimal time complexity. Intersection determined using bit arrays. In a single dimension, inserts, deletes, and queries should be in O(log n) time. Bitarray used to detect existence without having to... -

Class-Hashmap
Class Hashmap Code
This implementation uses a simple hash function that takes the modulus of the hash value with the size of the hashmap to get the index of the bucket where the key-value pair should be stored. It handles collisions by using a linked list to store multiple key-value pairs in the same bucket. The add method takes a key-value pair and adds it to the hashmap. If the bucket at the index returned by the hash function is empty, it creates a new linked list with the key-value pair. ... -

hashmap
A Golang lock-free thread-safe HashMap optimized for fastest access
A Golang lock-free thread-safe HashMap optimized for fastest read access. It is not a general-use HashMap and currently has slow write performance for write-heavy use. The minimal supported Golang version is 1.19 as it makes use of Generics and the new atomic package helpers. Reading from the hash map for numeric key types in a thread-safe way is faster than reading from a standard Golang map in an unsafe way and four times faster than Golang's sync.Map. -

Redix
A very simple pure key => value storage system that speaks Redis
redix is a very simple key => value storage engine that speaks redis and even more simpler and flexible. redis is very simple, sometimes we abuse it, so I decided to build a pure key-value storage system that introduces the core utilities for building any data structure you want based on the key => value model that is because I think that everything could be modeled easily using that model, so I decided to not to follow redis and all of its commands, you won’t find lpush, hset, sadd, … etc you will find a new way to do the same job but more easier and flexable, i.e, the well-known hset key field value command could be replaced with set key/field value, but sometimes you need to return a specific hashmap as key => value, but you run hget key field to get the key’s value and also it could be replaced with get key/field, but how could we replace hgetall key? I will say “it is easy”, let’s make the hget command work as a prefix scanner that scan the whole database. -

Cyclops
An advanced platform for writing functional applications in Java 8
Fast purely functional datastructures (Vector, Seq / List, LazySeq / LazyList, NonEmptyList, HashSet, TreeSet, TrieSet, HashMap, LinkedMap, MultiMap, TreeMap, BankersQueue, LazyString, Discrete Interval Encoded Tree, Zipper, Range, Tree, DifferenceList, HList, Dependent Map). Structural Pattern Matching API (deconstruct algebraic product and sum types). Improved type safety via the removal of unsafe APIs -- E.g. Unlike Optional, Option has no get method (which could throw a null pointer) -- New data structures do not support operations that would throw exceptions (you can't call head on an empty list for example). ... -

Joove
best way to script java code
This is a lightweight library all in one file that has the spirit of Guava or ApacheCommons namely to write Java code more readable and less formal constraints This library and centered on a class "var" that is unique type for the management of lists HashMap tightens or other types of data through simple manipulations can be traced between them (eg. A string becomes an array after a split etc .. .). Here we will have a "var" that contains a string remains a "var" that contains an array so the programmer does not have to worry to optimize the process or make converioni to treat the data later With this library is approaching to a typical Java scripting language, though not in the manner of Groovy ie with the introduction of an alternative language but simply board using java native but with mini wrapper to its usefulness. -

SPARGEL
An opensource Java graph library. Abandoned, ignore.
...This is achieved by extending graphs via properties in form of vertice and edge maps. Because these maps are an individual implementation depending on the graph datastructure used, they are more memory efficient than using a Java HashMap. Currently spargel is in its early stages, but will soon support more tasks. As now, implemented are: * Adjecency graph data structures * Algorithms: SSSP, APSP, Traversal, Min-Cut, Max-Flow, Many types of finding Components * Creating sub graphs, vertice and edge maps that use a function to implement their mapping. Spargel is released under GPLv3 -

Serializable Data Transfer Object/Generic Dao for J2EE
Dto.java and others classes - for data transmission from/to view (with EL - Expression Language" ) layer to/from business and persistence layer in J2EE application. Dto extends from HashMap class of Java API for encapsulate any type of information by key type:key_i.key_ij.key_ijk....: Any component in any J2EE functional chain can access to DTO if they know the key key_i.key_ij.key_ijk.... for object access. This project helps to decouple the data, business logic and persistence logic allowing portability between different frameworks gently. -
