BukkitCommons

NOTE: THIS IS A DEVELOPER PLUGIN. IT PROVIDES NO FUNCTIONALITY STANDALONE UNLESS ANOTHER PLUGIN DEPENDS ON IT.

BukkitCommons^ is a library of utilities designed to ease programming using the Bukkit^ API.

Build stats: Javadocs: http://agenttroll.github.io/BukkitCommons/

Features:

Extra collections, including HashStructures and abstract hashing structures, along with the implemented hashing API.
Concurrency utilities: Low-level access to locking structures, synchronization helpers, exchange channel (INDEV), and thread pool implementations (INDEV)
Asynchronous event framework that doesn't depend on the BukkitAPI, therefore, is thread safe
Miscellaneous tools: Formatted ASCII tables and abstraction barriers using Runnable
NMS access[INDEV], including protocol interceptors and channel writers, plus packet creation utils [INDEV]
Low-level access to sun.misc.Unsafe, wrappers (INDEV), math caches
Reflection (INDOC): Reflection wrappers help make your life so much easier, it uses internal sun.misc and sun.reflection APIs to further increase the speed of your reflection, benchmarks are included at my blog post http://agenttroll.github.io/blog/blog/2014/07/20/fast-reflection/ (will be updated)

Usage: Self-explanatory, JavaDocs are what you need.

If you still need help, here are some guides: - Reflection - Protocol (Working on Packet sending =D)
