An assortment of highly-specialized structures for use in a concurrent environment.

The documentation for this project is viewable online here.

Many of the data structures implemented in this library could easily be replaced by ConcurrentHashMap, however for as long as Valhalla is not a thing ConcurrentHashMap is more expensive than our solutions due to overheads that are incurred by autoboxing or simply the more design of the CHM.

All contributions of any kind are extremely welcome! Feel free to suggest, add, improve or outright redo sections of this library. Contributors are extremely rare within this desert so don't be shy to contribute even though you think you lack the expertise. Conversely, experts shouldn't stand idly waiting for the library to improve on it's own - I assume you already know that this does not happen.

However, when contributing please make sure your contribution would be compatible with your license.

The library is still pretty much in early development but it can be found under the https://stianloader.org/maven repository as org.stianloader:stianloader-concurrent:<version> the available versions are listed under https://stianloader.org/maven/org/stianloader/stianloader-concurrent/

This library depends on Java 8+ and Fastutil. Latter is used in order to allow to quickly swap between implementations of your data types.

A known alternative to this library is fastutil-concurrent-wrapper, however that library does not support iterators.
